You're not gonna find a bigger Hill fan than myself and I'm in no way advocating for his departure. But if what Kori's said in the past is true, that the Spurs view Hill to be a 2 (and I have no reason to believe what she says isn't true), the possibility of acquiring Rush (a guy who's 6-6 in shoes and has nice length) and the 10th pick might be the right move to make, even if unpopular.
Rush could be one of the best potential 'Centerpieces' they could find for next year, as he's a solid defender and just got done shooting 40-percent from three. And if they're high enough on someone like George ... they could have the size and length set on their perimeter for a long time.
DX currently has Davis off the board at 10 and their doesn't seem to be a lot of separation between the prospects in that 10-20 range (DX's current 10-20: Ekpe Udoh, Patrick Patterson, Luke Babbitt, Avery Bradley, Cole Aldrich, Gordon Hayward, Paul George, Damion James, Hassan Whiteside, Daniel Orton, Larry Sanders), but the combination of Rush and one of those prospects could very well address more needs and put them in better position, both short and long-term, than Hill. Could.
I really don't want to see Hill go. He's one of my favorite players. But there's an argument to be made that it'd be best for the team if this deal could be done.
