Defensive Charting vs. Oklahoma State

Defensive Charting vs. Oklahoma State

Some quick thoughts on the defense against Oklahoma State– first here’s the defensive boxscore:


  • Guarding Juwan Evans: Evans is a really talented lead guard, who’s especially adept at utilizing the high-ball screen. While the comparisons to Chris Paul may be a bit overstated, Evans did consistently make good decisions following a ball screen (and the Cowboys set one for him on nearly every possession he was on the court). Luckily for the Heels, his teammates (a mediocre group in general) missed almost all the opportunities he created for them. That said, UNC did a great job of forcing Oklahoma State into suboptimal shot attempts out of its PNR offense– no open 3s for Forte or Carroll, lots of mid-range shots for OSU bigs, no easy shots at the rim, etc.
  • I charted 39 OSU ball screens, most for Evans (and most defended by Berry), with the following results: 8 made field goals (1 3-pointer), 19 missed field goals (7 3-pointers), 3 turnovers, and 9 offensive resets. Shockingly, UNC did not commit a single foul when defending a ball screen. Even accounting for some good fortune (missed clean looks), 17 points allowed on 39 ball screens is a really, really good number.
  • Evans scored his 30 points in the following ways:
    • Berry-Bradley ball screen: 6 points
    • Britt iso: 5 points
    • Berry-Hicks ball screen: 4 points
    • Berry iso: 4 points
    • Berry-Meeks ball screen: 3 points
    • Woods iso: 3 points
    • Woods-Bradley ball screen: 2 points
    • Hicks iso: 2 points
    • Transition: 1 point
  • As seen in the %Poss numbers in the defensive box, both Berry and Woods had busy defensive games. Berry gave up some points, but played a really effective defensive game. I credited Evans with 5 “contested” makes– he’s a great scorer who made some well-defended shots. Woods wasn’t as effective, but that’s to be expected in his first matchup against an elite collegian. The defensive boxscore probably overvalues his performance on that end (his On-Court DRtg is probably a more accurate reflection).
  • Kenny Williams pitched a shutout (he did opt to box out an OSU big following a defensive rotation, allowing a tip-in, but I assigned that hoop to the “team” since Williams made a good decision to help out Meeks following his rotation). Phil Forte, a lights-out shooter who’s had some huge games at OSU, was unable to get any clean looks thanks many to the defense of Williams and Britt. While Williams didn’t get credited with many defensive stops, preventing scoring opportunities in the first place is often just as valuable.
  • Meeks defended the ball screen well, and generally played hard and smart. He altered several shots as a help defender. I assigned 7 of OSU’s 19 offensive rebounds to Meeks, so that’s obviously a concern. He was boxing out consistently, but struggled to win contested defensive rebound opportunities (although he got a hand on just about all of them– enough to prevent easy put-backs in most cases).
  • This was easily Bradley’s most active/disruptive game as a Heel in terms of deflections, forced TOs, etc. He figures to get better and better as a help-side shot-blocker, too, as the season progresses.

  1. Your charts are a bit on the tiny side. I keep thinking they’re somewhat a thumbnail and it will be full size once I click on it… Not a huge deal as I end up opening them in a new tab and enlarging the picture, but I thought I would mention it anyway. Good information.

    1. Yes, this is bothering me, too. I’ll work on a better way to present/enlarge the charts and hopefully have a solution ready for next time.


      1. Adrian,
        Have you tried increasing the size % in the bottom right corner of Excel, then copying and pasting after you enlarge the spreadsheet?

        Great work, as always. Go Heels!
