The defensive effort against Iona was, understandably, much better than against Duke. Feel free to dive right in if you're used to this sort of thing, but if you want to read up a little more on the science behind these numbers, check out this link.
I had a hunch that Andrew White didn't get a lot of playing time because of his defense, but the opposite seems to be the case. He didn't have a ton of opportunities to show it, but he was also the only Jayhawk who didn't get scored on. It must be something to do with the fact that he plays the same position as Wiggins, but two lanky threes who can defend well seems like a good problem to have. Though, to be fair, it's unwise to make judgments about defensive ability based on one game.
I am selfishly happy that my eye test telling me that Perry Ellis was a good defender has been confirmed (so far). Another nice game from him.
Jamari Traylor played very well as well, and it's tough to describe how active he is on that end of the floor without watching him.
Wayne Selden had a rough game here, though to be fair there were a couple possessions where he got a little out of position because someone else got beat (which brings me to a bit of a style point: if a teammate gets beat and Selden slides over to help and gets scored on, it's a bit of a judgment call as to whether to give the whole make to the player who got beat or half to each of them, or a three fourths/one fourth, but if Selden overhelps when he shouldn't and then he gets scored on, I usually give him the entire make).
Andrew Wiggins is a weapon.
