I'd be surprised if Knight were there at 12, but I can see Walker being there.
I dunno, maybe Knight is worth the 6th or 7th pick, but I've been pretty sure to this point that the Jazz are looking for another wing with their highest pick. That said, if we keep both picks, then I think one of them should be spent on a PG. Knight's size is intriguing; he'd be able to guard 2 positions, whereas Knight can't say the same thing. Knight could be a very reliable shooter.

I'll vote for Knight since I think he'll be the better pro, but he'll also cost more and hasn't proven he has the guts of a good Kebab.
