I'm not so sure about Hibbert in two areas.... it seems that he rarely plays motivated, and he has said on numerous occasions that he wants to play all 4 years at Georgetown (he is a Jr, isn't he?). As for the first point, I can't say that I've seen all his games, but those I have, he doesn't seem to be a dominant player for being a legit center sized college player. Not real confident that translates well to being a solid starter in the pros. 7'2" is 7'2... but he's not gonna run with the Amares... and he's not gonna throw his weight around with the muscles... and he doesn't have the range of Z.... personally, I would pass on him.
As for Love, if he came out, him I would take a chance on if that was a team need.... but I'm not sure that he fills a team priority. Good player, and I think he will be a solid pro... but again... do you go for best talent available, or to fill team needs? Hibbert might fill a future need better... but I'm just not sold on him as a pro.
