If he is willing to come for the minimum, sure, but I am not all that excited about the idea. It is a very big personality to bring into this lockerroom, and could cause major problems once Perk returns.
I think, unless the C's are lying about how bad Perk's injury is, they are much better off going to get a veteran big man like Kurt Thomas, Rasho Nesterovic, Fabricio Oberto, or someone else of that ilk to hold down the fort for a few months.
Last year they did just fine with Shelden Williams stepping in for Glen Davis, so I see no reason why they can't do the same thing with Perk...particularly with JO, who should have more left in the tank than Sheed, as well as a much more healthy KG.
