against Gonzaga’s bigs and other top bigs is not outstanding. Yes, against most schools he definitely alters shots and is currently leading the WCC in blocks with 2.0 per game.
However:
Defensive rebounds: Haarms #27 (behind teammates Lohner #7; Harward #18 and Barcello #24)
Steals: not listed in top 37, although Barcello comes in at #17; Averette at #22 and Lohner at #37
For Bigs I like: USF’s Dzmitry Ryuny: #23 in steals; #5 in blocks and #10 in rebounds including 4.7 defensive rpg
Ryuny’s defensive stats only trails Haarms in blocks. Unfortunately they don’t list altered shots
