McClung is making me look like a genius for saying how well he has pitched except for that one game early when he was asked to take one for the team, way back in early April. Other than his fatigue issues in the 5th of his first couple starts (see Joba for how hard it is to go 5 right away), he's been simply astounding. Time will tell if he's able to continue this once the scouting reports are issued and such, but right now, he's proof that when in doubt, go with the guy who is pitching the best, and worry about the rest later. As for Weaver, he would not be replacing Seth if he were brought up. As Rev Jackson would say, this question is moot.
