I would never trade Weeks for Roberts. There's still a lot of potential in Weeks, whereas Roberts pretty much is what he is, a second baseman who's going to hit around .300, get on at a decent clip, hit 10-12 HR, steal bases, and play a below-average second base. I would certainly trade for Roberts as a rental, though, because I do think Weeks' wrist is hurting him and Roberts would solidify the position. But, the asking price for Roberts is going to be too high for the Brewers, I think.
