What a Clemens decision to return to the Astros does is help them focus on getting something else at the trading deadline. A starter is premium, so if you can get one as a free agent, then you can focus on perhaps a different position that can help you. See: Huff, Aubrey last year. MoBerg was in a swoon and the fact that Clemens came back helped the team go get Huff. Much as some will say that AH didn't produce, it was better than going with MoBerg the way he was swinging it.
