I think he had better worry about making the playoffs first. Actually, the Cubs have needed another lefty in the bullpen since Cotts imploded. Gorzelanny and Marshall add a lot of depth to the starting rotation in case of injuries, poor performance, or team matchups. Also, don't forget the impact of this trade on the future. If Grabow doesn't meet expectations, he could net the Cubs 2 draft picks. Marshall and Gorzelanny could step right in as possible starters if Harden isn't resigned. Who's going to sign Grabow if they have to sacrifice 2 picks to get him? Someone would be dumb enough.
