Someone coming off a long break without playing much is always liable to pull a muscle. Sounds to me like someone has not been doing their job of managing his activity or making sure he is properly warmed up. Who is our strength and conditioning coach anyway?
While it would be better for the Hawks for him to be an insurance write-off, I would welcome Claxton back if I thought he could produce on a consistent basis. Even still, a pulled hamstring is not what will end his career. If he can come back from the surgeries, he can come back from the muscle pull. That said, I do not expect much from Claxton on a consistent basis.
I'd like to see him ride the bench until absolutely necessary for him to play. You know.....the month or so when two someones vital get hurt and we need an offensive spark. Just in time for everyone to be ready and primed for the playoffs.
