Offensively: Somewhere in the middle between Spring '12 and Spring '13.
Defensively: What you saw in both Spring '12 and Spring '13.
In other words, Avery is very likely to continue to be the elite defender that he has consistently shown all along.
And on offense, he'll probably settle in somewhere between the the hot-shooting of 2012 and the mediocre (post-shoulder surgery) shooting of 2013.
Note - the two samples are very similar in size: 1368 minutes in 2012 and 1435 minutes this last season.
If he regresses to the middle, he should end up as around a 47-48% eFG% & ~36% 3P%, ~77% FT%.
If he can shoot at those levels (which are consistent with how he's shot over the larger course of his career when you include HS, NCAA & D-league) then with his elite defense, he's a solid, plus-quality starter.
If he can't get his shot back up to those levels, then the worst case is that he's a solid bench defensive role player.
Fortunately, he's still on his rookie deal for the next year (plus team option after that, I think) so we have time to figure out which of those two roles he'll fit long term.
