No...
Bradley is a nice player. He's a 15 PPG scorer at the guard position, he's an outstanding defender, and he's a walking Tommy Point. I IMHO he's also shown significant improvement this year as a passer, ball handler and decision maker.
He's not likely to be a star any time soon, but he's been a pretty solid starter and arguably the best player on what is potentially a playoff team.
Draft picks in the 10-12 range are generally pretty risky, and from what I've read this upcoming draft is looking to be a very top heavy one. The chance of drafting a guy as good as Bradley (or even nearly as good) is not probably.
Not worth the risk imho. I absolutely love the defence that happend when Smart and Bradley are on the court together, and I think that's about the only thing thats allowed this team to compete for a playoff spot throughout the year.
