Who's out there right now? Kenyon Martin? I'd still take Pau over him. Or trade him for a defensive minded PF? Then what do the Lakers do with Jordan Hill next year?
If we got someone like Kevin Love for Pau (huge reach), or a good bench scorer, I wouldn't mind Kenyon Martin playing backup center. But of course that would depend on who we got.
Or say the Lakers trade for Josh Smith, a big reach again, I know, but just go with me here, as he's a defensive minded PF. They could just play Smith at Center along with Sacre, Clark, and MWP for blips and everything would be fine. Jordan Hill could then play backup C next year or backup PF, depending on the roster.
