I find it hilarious that people are arguing over Daye, a guy who has had plenty of opportunity to show he's an NBA basketballer and failed at every turn. And he's certainly not a 4 of any description, stretch or otherwise - his rail-thin body (a body type that simply does not add weight, regardless of what you do with it) would get abused in the post by any half-decent offensive 4. Bonner, OTOH, has the frame and willingness to bang that makes him a decent, if limited, defender.
Time Daye headed to Europe IMHO.
