I'd rather keep Perk and use the MLE on someone. That'd be the logical way to do it no?
Well, it depends. I don't know what the "Logical" way of doing it is, if we don't know what we can get for Perk, as well as what the going rate will be for veteran big men like Camby or Brad Miller as stopgaps.
For example, if they can get a top 5 or 6 pick for Perk (unlikely, but you never know), then the logical thing would be to trade him. If you can get a young player, with a higher upside on a rookie deal (say, Perk for Michael Beasley), then again, the logical thing to do would be to trade him.
However, if you are just going to get a late first rounder, and a borderline rotation guy, then of course you hold on to him, get another year from him, and if he demands too much money, let him walk.
Really, I think its impossible to know what will happen with Perk, but Danny would not be doing his job if he is not exploring every option, which includes trying to trade him.
