Reality is harsh. The point (pun intended) is that Burke was a poor shooter last season. And he showed very little improvement in his second SL. If that was the ONLY concern then I'd hope he'd improve it. But he's also short, plays slow and doesn't get to the rim (which negates the one thing he DOES do well...shoot FT's).
Trey is going to be a solid backup or a starter on a very weak team, nothing more. The sooner all of you realize this, the better. Fortunately, I think the FO already has and had no hesitation drafting Dante.
