Charlotte are indeed a mess, but I don't think the franchise could really afford a supermax when they are already locked into a bunch of bad contracts and going nowhere. They should have been proactive and traded Kemba earlier for some assets, cleared their bad contracts and tanked last season.
I really like the fit for Kemba on the Celtics, but I do wonder if they would have been better off in the long run spending some money on a free agent centre and allowing the offence to be run through Hayward, Tatum and Brown? Might be one step back next season, but Tatum and Brown could really benefit from the increased responsibility.
If Kemba does indeed sign, there is some suggestion the Celtics are the team Houston has a deal with to offload Capela. That would be a pretty nice offseason rebound by Ainge if he could make that happen, but its dependent upon Butler wanting to go to Houston and Philly being willing to make it happen and I just don't see it.
More likely, the Celtics find a bargain basement bin centre - Noel, Vonleh, R. Lopez - and hope Rob Williams, Grant Williams and maybe Theis can all contribute some good minutes.
