Just checking in . . .

. . . to let you know that, while blogging activity has been non-existent here since the end of the season, things will be picking up again in the fall. I've been out of the country for the last 2 months, and have just recently returned.

I'd like to thank Tom Gower for so ably filling in for me while I was gone. Hopefully, he'll be willing to keep contributing in some capacity next year. I'd also like to thank HoyaJake, for all of his hard work this past season working out player +/- numbers - it seems to have become one of the most popular stats pages.


Now that I'm back, I'll be trying to finish running the numbers for the end of last year. I'm also working on some more analysis of individual player performance, but that is only a work-in-progress, and one that is a low priority for me. No promises if and when that will be forthcoming.

For now, the best sources for Hoya news are:

These are always linked on the right side (although you may have to scroll down a bit).

Cheers!

Analysis: Davidson 74, Georgetown 70

Well, to use the HoyaTalk parlance, Edited. Davidson recovers from an 11-point halftime deficit, and being down 17 early in the second half, to beat the Hoyas, 74-70, and end their season.

Let's run the numbers:

                        Offense                            Defense
1st Half 2nd Half Total 1st Half 2nd Half Total
Pace 31 32 63

Eff. 123.7 98.7 110.8 87.9 144.9 117.2

eFG% 78.6 72.5 75.6 30.0 59.3 43.9
TO% 26.0 37.0 31.7 9.8 6.2 7.9
OR% 33.3 27.3 30.4 31.8 38.5 34.3

FT% 50.0 42.9 47.1 75.0 83.3 80.0

Some relevant numbers highlighted, but no other commentary from me right now. I'll probably do an HD box of this game some time in the next couple days, maybe even broken down by half.
---------
UPDATE (3/23/08, 2000 CT): Just one thing to add for now:

OffEff v.Expected DefEff v.Expected
110.8 +4.5 117.2 +20.8

Once again, the offense looks bad, and certainly did some bad things in the second half, but the real problem came on the defensive side of the ball. Davidson hit 10 of 13 on 2's in the second half. Make that 5 or 6, like a Hoya opponent normally hits, and I'm figuring out how I'm going to get all my work done and still go to Detroit.

Analysis: Davidson Preview

Check out the middle column. One of those things is not like the other:


Opponent Off v.Exp Def v.Exp
UNC 88.3 -12.6 93.5 +18.8
Duke 99.2 +1.1 107.4 +0.0
Charlotte 99.3 -10.5 102.9 -8.9
UCLA 99.1 +6.5 118.0 -9.2
NC State 96.1 -13.9 97.5 +0.0
Gonzaga 118.7 +16.3 114.3 -6.5

The above is the list of the top 100 (ok, NC State is #102) teams the Davidson Wildcats have played this year. They've notably outperformed their expected offensive performance in one of those games. They've won one of those games. Somehow, those happen to be the same game. They've notably outperformed their unexpected defensive performance in only one of those games, which happened to be UNC's first game of the year and Davidson's second--pardon me if I discount it.

Now that we've seen a little about what they do against better teams, let's check out their overall profile. They're a good but not elite team at both the offensive and defensive ends of the court. The keys to their offensive performance are:
--Good shooting. They shoot a lot of 3-pointers and shoot them well for a team that shoots them often. They're also even better, comparatively, on 2's.
--They don't turn the ball over. Yes, that's a familiar story, since that was UMBC's best attribute as well. Yes, those same Retrievers who turned the ball over 50% more against the Hoyas than they did regularly, and more than they had in any game they played in calendar year 2007.
--The Wildcats also don't get their shots blocked. I suspect that's a function of taking outside shots. Also, probably part of playing in a lousy conference (see above list of decent teams played).
--Except for Boris Meno (who really shouldn't ever shoot a 3), everybody they play is at least an average offensive player.

A couple more interesting features:
--They don't get fouled. Like, at all. Curry is a big reason behind this. Especially for a big shooter, he doesn't take many free throws.
--Their usage pattern is weird. Richards and Curry each play on average over 32 minutes a game. Sander, Gosselin, Meno, and Lovedale play a little over half the game on average. To complete the rotation, Archmabult, Rossiter, and Barr play 12-15 minutes a game. This changed a little on Friday against the Zags. Gosselin and Lovedale played more, Barr and Meno played less. This will probably vary a little on matchups, but it's something to watch for.

On the defensive side:
--Their opponents miss foul shots. Maybe they foul big guys. Maybe they're lucky. Maybe it's a function of playing bad opponents. Who knows-as far as I know, this is one of the more unexplained areas of figuring out tempo-free stats.
--They force a lot of turnovers. That's not surprising from a guard-oriented team, but they're only a little above-average w/r/t steals. Somebody who's watched them more than I have can probably say something sensible about this and why this is. Having a fairly high % of opponent TOs is something that's been fairly constant between games vs. good and non-good opponents, too, so it's not just a function of beating up weaker teams.
--They're surprisingly good on the defensive glass, to the tune of 23rd in the country in terms of preventing offensive rebounding. This was the key to their second half success against Gonzaga. The Zags hauled in 57% on the offensive end in the first half, and 19% in the second half, and efficiency fell accordingly, from 130.8 to 99.5. They're only average on the offensive glass, though, and were very average both halves against Gonzaga.
--There's no particular area defensively where they're very below average. They send opponents to the line a little more than average, but that's really it.
--Opponents tend to be perimeter-oriented. Not so much so as the Hoyas normally are, but a bit compared to the average. I don't have time to run the full opponent numbers, so it could just be who they've played (I don't believe that stat is opponent-adjusted) or that whole "playing bad teams" thing rearing its head again, but it's out there. I suspect this maybe a defensive strategy-Gonzaga isn't a three-point heavy team, but took half their shots in the first round from outside the arc. I don't think it's as important as the rebounding figures noted above, but part of the Zags' dropoff was going from 8-15 on 3's to 4-12 in the vesper half.

Keys to the game?
--[Insert normal verbiage about rebounding. If rebounding is vaguely normal/equal, fine.]
--[Insert normal verbiage about outside shooting. If Hoyas shoot really low and/or Wildcats shoot really well, not fine.]
--[Insert normal verbiage about good players taking good shots, and preventing good looks by other team.]
--[Insert verbiage about Stephen Curry.] The Hoyas can win limiting him to 15, and can win "limiting" him to 40. People who can speak more knowledgeably than I about basketball can answer which of these alternatives is better, and the coaching staff (who definitely fall into such category) will have to make the determination, to the best of their and the team's ability.

The Hoyas are a better team than Davidson. But, Davidson isn't UMBC, and the Hoyas aren't so superior they'd almost have to try to lose the game. The Hoyas are good enough that if they play a good game Davidson will have to be pretty close to perfect to win. Davidson's bad enough that if they stink up the joint the Hoyas will assuredly win. Probably something in between will happen, and the Hoyas will likely win, but it wouldn't be a shock to see Davidson win. KenPom says 67-61; I'll go with 68-63.

UPDATE (3/24/08 2101 CT): "Use the came" instead of "lose the game"? I swear, I was sober when I did that. Wonderful "disembodied hand" syndrome.

News: Georgetown Beats UMBC, Will Face Davidson Sunday

The Hoyas today advanced to the second round of the NCAA tournament, topping UMBC, 66-47. Not a pretty game, but the Hoyas did what they needed to do to win. No full box available yet, but here are some of the key stats:

  • Hoyas 64.3% from 2-point range, including 69.2% in the first half.

  • UMBC 33.5% from 2-point range.

  • Hoyas 42.9% from the charity stripe. Not a great performance.

  • Hoyas turned the ball over on 24.8% of possessions. Tough to win if they do that again on Sunday.

  • Most shots: Wallace, followed by Hibbert. Efficient players taking the lead offensively! I approve.

  • When your blogger takes a half day off work he intends to be home in time for the Hoya game, not work until 6:30. /Whine off.


I'll be back tomorrow (Saturday) with more on what you can expect from the Davidson Wildcats, and hopefully a full box score as well.

UPDATE (3/22/08, 1915 CT): No full box still, so I'll just post what I have.

Analysis: Keys for the Hoyas

Check out Georgetown's team stats this year. Compare them to 2007. Note the offensive and defensive ratings. Note how 2007 was a better offense and 2008 was a better defense. Note the key to winning last year was offense. Take a look at those Georgetown team pages again, scrolling down to the individual stats. Note 2007, when every player who played at least 30% of the time had at least an average offensive rating, and the three of the top four by Possessions used were 114.8+. Note this year, when after Hibbert (who's only really efficient instead of awesomely so this year), the two most-used players (Summers and Sapp) are only a little above average offensively. There's a bigger gap in Poss% until the next tier of Wallace, Freeman, and Ewing, who are all good offensive players, but who only shoot on about 18% of possessions-below-average use.

Those are the overall stats, but what's happened recently is probably more important. So, I took the individual splits for the last 5 and last 10 games and averaged them. No, this isn't an ideal statistical method, but it gives us a good snapshot weighted towards recent performance. Let's run some numbers:

Player   %Min  ORtg  %Poss
Summers 75.0 96.2 23.2
Hibbert 68.9 120.1 26.7
Ewing 60.1 99.5 19.7
Wallace 89.7 129.8 17.1
Sapp 64.5 112.3 20.3
Freeman 63.8 111.2 16.9

There's an extra column there, which I'll return to later. Note the recent trends:
--Sapp is shooting less, and shooting better. He's shooting 52.8% on 2's and 46.3% on 3's, up from 47.6% and 40.7%, respectively. Part of this may be hot shooting, but I think part of it is excellent shot selection.
--Ewing is shooting more, and shooting worse. He's 64% for the year inside the arc, and 46% lately. Outside the arc, the same: 22.5% recently, and 29.5% on the year. Any time PE2 shoots from outside, it's a gift to the other team.
--Among the six key players, the key to the Hoyas' offensive performance will be DaJuan Summers. He uses a lot of possessions and doesn't use them very effectively. His FG% has been fine, better than average lately, but an already low 3FG% of 33.7 has been even lower, 30.3%, lately. Plus, he's turned the ball over 26.2% of the time lately, up from 18.8% on the year. Note a reduction in turnovers was one of the keys to the Hoyas' tourney run last year.
--Wallace and Freeman are both playing well offensively, but are participating slightly less than their already below-average %possessions.
--Among the lesser-used players, Macklin and Rivers both have fantastically high (38.6% and 37.5%, respectively) recent turnover rates, and have really bad ORatings because of it. Those either need to stop or they need to sit on the bench if at all possible. Otherwise, you're just giving away possessions, and it's hard to win in the tourney when that happens. Just ask Kent State, which turned the ball over on 43.6% of first half possessions today to fall behind 31-10.

Ok, minutes. Jeff Green last year played 83% of the time, or about 33:20 per game. Who's been getting that time? Ok, Freeman of late has been getting a bit of it, but he's been playing about 25:30 a game. That leaves 8 minutes unaccounted for. Another key difference: Jessie Sapp is playing less, to the tune of about 7 minutes a game. Instead of 8 minutes to make up, that's 15 minutes. And the lion's share of that time, about 10 minutes, has been going to Patrick Ewing, Jr. From a size perspective, that's better than giving the minutes to Freeman. From an offensive efficiency perspective, well, see above.

Summary: to do well in the NCAA tourney, the Hoyas need a high usage player other than Roy Hibbert who does well offensively. Most likely, that's DaJuan Summers. If he plays well, the Hoyas can advance far. If not, then the Hoyas may well not advance to the second weekend.
