There's been a lot of this in this and other threads, but I gotta say, I'm just not seeing it. Yeah, he scored 9 points last night, tied for third on the team, and Mason Gillis scored bupkus. But Evans literally didn't do anything else. He played for 17 minutes, and he had no rebounds, no assists, no blocks, no steals, and no defense (his DBPM was -4.5 for the game, and he's -0.9 for his short college career). I'm not seeing greatness there quite yet.
Now last night, Gillis didn't score and didn't do too much else, either, but he did grab 5 important rebounds and was third on the team with that. While Gillis provided positive defense, he was a negative on offense on a night where offense was our problem. But Gillis has a long track record of providing both solid defense and competent, if one-dimensional, offense. Offensively, Gillis is shooting nearly 150 points off his career average from 3pt range on a small sample size this season (23 attempts), but his career 3pt percentage is still almost .400. If he had just 3 more makes, he'd be within 10 points of his career average. If think his poor shooting so far this season has been mostly a question of sample size. His usage rate is spot-on with what it was in his Purdue career.
Also, worth noting that that this still probably isn't a head-to-head, either-or situation. Although I haven't gone to explicitly check, it seemed to me that Gillis and Evans spent about half their game time on the floor togeether.
Evans will get better. But based on how he's done last night and so far this season against mostly lower-level competition, I just don't see how he has yet earned much floor time in close games or against big-time teams. Perhaps soon, but he's just not there yet, IMO.
