Does getting a No. 1 seed matter?

(goduke.com)

On Selection Sunday morning, I wondered aloud why people still get so wrapped up in the question of who gets a No. 1 seed when it’s been six years now since Ken Pomeroy showed that it really doesn’t matter in basketball terms.

The first batch of answers to my query muddled the distinction between cause and effect. Yes, No. 1 seeds have a great track record of getting to the Sweet 16 and the Final Four and winning national titles. Top seeds also tend to be the best teams.

A far better response I received was that arguing about who should get a No. 1 seed is fun and, besides, receiving a top seed is a really cool honor. No disagreements there.

Perhaps we could talk about No. 1 seeds in that vein henceforth, more like an MVP award than as something dispositive to title hopes going forward. It’s a venerable honorific with some nice history behind it, and it provides its own ready-made zero-sum boxing ring for debate. That’s fine. Continue reading →

Welcome to the strongest Sweet 16 “ever”

In a normal year, Auburn would be a 50th percentile Sweet 16 team. In 2019, however, the Tigers rank No. 13 among remaining teams. (Wade Rackley, Auburn Athletics)

We’ve suspected for weeks now that there’s an unusually dense concentration of big swaggering capital-letter Great Team behemoths roaming our hoops landscape in 2018-19. Pick your flavor and choose your boundary line, but, speaking generally, this field’s top 10 or 11 teams together constitute an oligopoly of hoops hegemony the likes of which we don’t often get within the confines of a single season.

Well, it just so happens that all of those teams, every one of them, won two games during the first weekend of the 2019 NCAA tournament. Not to be outdone, so, too, did the tier of teams right below the big guns.

When you put chalk together with behemoths, you get a Sweet 16 that fairly blows its predecessors out of the statistical water.

Your 2019 bracket requires knowledge of shot volume

(gozags.com)

Shot volume is just one half (how often you shoot) of one half (offense) of basketball, so it’s not the alpha and omega of the sport by any means. Then again, it’s rather under-discussed.

You can’t show shot volume on YouTube or Synergy, coaches can’t diagram a play specifically to get an offensive board, volume doesn’t get “chess match” heuristic privileges, and avoiding turnovers is supposed to occur as a matter of course.

That’s all well and good, but, just like with shooting accuracy and defense, some teams are exceptionally good at shot volume. If we want to understand these teams, we should consider the frequency with which they attempt shots.

Tuesday Truths: Final reality

Welcome to this season’s last installment of Tuesday Truths, where I looked at how well 108 teams in nine conferences did against their league opponents on a per-possession basis.

Come back, Zion

This post has nothing to do with Duke or Zion Williamson, Tuesday Truths just really wants to see what the freshman can do at full speed in an NCAA tournament that should be heavily populated by swaggering 2015-style beastly opponents. Hurry back, sir. (USA Today)

Final results, conference games only
Pace: possessions per 40 minutes
PPP: points per possession Opp. PPP: opponent PPP
EM: efficiency margin (PPP – Opp. PPP)

Clemson is the anti-Indiana. Unlike the wacky and erratic Hoosiers, the Tigers were more or less utterly predictable based on the quality of the opponent.

Indeed, not to put too fine a point on it, Brad Brownell’s group effectively strip-mined the bottom of the ACC for that borderline-Virginia Tech-like scoring margin of theirs…. Continue reading →

Tuesday Truths: AWOL from Bubble Watch edition

Welcome to this season’s penultimate installment of Tuesday Truths, where I look at how well 75 teams in six conferences are doing against their league opponents on a per-possession basis.

I don’t think Virginia gets enough credit for its defense

(virginiasports.com)

Through March 4, conference games only
Pace: possessions per 40 minutes
PPP: points per possession Opp. PPP: opponent PPP
EM: efficiency margin (PPP – Opp. PPP)

ACC                       W-L   Pace    PPP   Opp. PPP    EM

12. Notre Dame           3-13   65.2    0.97    1.09    -0.12
13. Georgia Tech         5-12   66.3    0.91    1.04    -0.13
14. Pitt                 2-14   67.2    0.95    1.09    -0.14
15. Wake Forest          4-12   68.3    0.93    1.15    -0.22

AVG.                            67.4    1.03

Perhaps this falls under the heading of a blinding flash of the obvious the day after a team sinks 18 shots from beyond the arc (in a game with 59 possessions, if this had been a North Carolina tempo, madre de Dios), but it is of course long past time to retire the “I don’t think Virginia gets enough credit for its offense” announcer trope.

Actually, at the moment, said offense is (very slightly) better than the D relative to the respective ACC means. Continue reading →

On rebounding

(Mike Carter, USA Today Sports)

We live at a time of televised analytic plenty, yet, somehow, you still see rebound margin numbers flung up on the screen during this or that telecast in 2019. That makes me grit my teeth at the blatant luddite behaviors on display, of course, and, well, I’m right to do so. Rebound margin really is meaningless, an ersatz and mislabeled tribute paid to teams that alter shots yet refuse to go for steals and/or charges (with all of the above, preferably, transpiring at a fast pace).

In partial defense of my well-intentioned graphic-making brethren and sistren, however, I will additionally confess to the following. I’ve been mulling just how peculiar rebounds really are for a while now, and (this may say more about me than about rebounding) I’m still not sure I’ve found solid ground on this particular subject.

Here’s what I think I think….

I’m not a fan of whole-season rebound percentages in college basketball
Leave it to the sport’s endearing and enduring idiosyncrasies to overturn perfectly sound axioms regarding sample size. Continue reading →

Tuesday Truths: Salute to concision edition

Welcome to this season’s first installment of Tuesday Truths, where I look at how well 75 teams in six conferences are doing against their league opponents on a per-possession basis.

Editor’s note: Tuesday Truths 2019 refuses to play along with your bourgeois time-slavery plastic fantastic Madison Avenue thing by being updated weekly like its name would, um, logically imply. It will instead will appear here and there, now and then, to this one and that one. Also, with today’s post, Tuesday Truths has now made an appearance for 11 consecutive seasons under two different names and across three different sites. Huzzah, The Streak! Take that, KU!

Duke is a rather well publicized team, and one of Mike Krzyzewski’s players in particular is possibly the best bridge we’ve ever seen between shoe sales and analytic swoons. But we here at Tuesday Truths are all about equal time, so let’s give it up for Louisville. Continue reading →
