Ever since Deng came, the Cavs don't have as many mismatches to be taken advantage of, so that was moot now that they're forced to focus on the ones we really have.
Meanwhile, there are 7-10 starting power forwards who have center size. Pau, Jason Thompson, Aldridge were included in that list. We already faced guys like Duncan and will face another in Dirk VERY soon.
I'm not going to say if Tristan is worth more than a 3rd big at this point, because we need 1-2 more seasons to see if he gets anymore bag of tricks (like the desire to take a jumpshot). But he has gotten stronger from the looks of it (the Manimal looked outmatched despite last season) and ends up playing within himself to get those 12-10 a game. He outplayed J.J. (positioning, rebounds, movement) He was communicating. And most importantly, he's not stupid.
The board here has a rapid-fire like opinion of the guy, but realistically, is this it? If it is, then he'd be a sixth man type forward with a great chance to become our Andy or Andy 2.0. If not, the sky is the limit.
