Tre showed flashes last year of being a physical post able to score some, agree with you that I thought he’d flash more this year.
I "like" Tre in general but he has his issues. When he gets good passes, especially hot passes, he has a tendency to bobble the ball. When you're a big man you are at an immediate disadvantage when you can't corral passes cleanly (Rob also has a similar problem at times, but to a lesser degree). I think this sabotages some of his offensive potential.
But he's also doing a lot of the BRE stuff from last year, that is forcing up shots that are off-balance, low-percentage shots. There was one in particular within the last couple of games where he bowled into the lane, threw up some complete BS, and missed everything by a wide margin. To be fair he's not the only one doing it right now but it's a consistent problem.
Probably my biggest frustration with Tre is he is a physical specimen yet routinely gets jumped over (poor timing) or out maneuvered for rebounds. He's built, has a 7 foot wingspan, and can jump. Tamu made him look really bad yesterday on balls he was in position to grab. This is something that should, at least theoretically, be in his control.
