Lopez would be a massive upgrade and certainly fills a need on the team, but I'm not sure what we'd have to part with in order to facilitate the trade, and his injury history definitely gives me pause.
But for everyone that's getting all up on Tyler Zeller's jock this year... you'd spend the rest of the season completely hot and bothered if we managed to snag Lopez. He might be the most offensively talented center in the league right now (of course, he can't defend, or rebound).
