This doesn't have anything directly related to the Boston Celtics, but it is a good example of a GM (who happens to be a former assistant GM of the Celtics) that is cutting costs in a rebuilding effort. Caron Butler was just picked up (to make salaries match) in a trade this offseason that landed the Suns with Eric Bledsoe. Now they are dumping Butler and his $8M salary on the Bucks, who actually want to use Caron for basketball reasons.
The Suns will reportedly trade forward Caron Butler to the Bucks in exchange for guard Ish Smith and center Viacheslav Kravtsov, according to an Arizona Republic Wednesday night, with the deal expected to be consummated within 24 hours. If the trade goes down as reported, it would cut roughly $5.5 million from Phoenix’s payroll and puts them in the vicinity of the league’s $52.8 million salary floor.
So basically the Suns are dropping a salary on a guy they didn't really want in the first place, they aren't picking up long term salaries, and they get to take a flyer on two young players. Not bad.
Consider this as an example of something the Celtics could do if they are so inclined. For example, if a team wanted to add a rebounder and had enough cap room to get a deal done, they could swap a few players for Kris Humphries. It is a no risk deal since he's on an expiring deal but it might be hard to find a team with the correct amount of cap room to absorb $12M. They'd have to be sending some amount of salary back to Boston (preferablyon expiring deals unless the players are good enough to be part of the rebuild process) to make up the difference between their cap space and Humphries' deal.
Just food for thought.
