The Braves missed the playoffs because of how they used Medlin. They got to the wildcard game, but if he had been pitching from the beginning of the season, they could have won the NL East.
I think its clear they should have went down the same path the Braves went w/ Medlin. Start him in the bullpen, gradually amp up his innings and then have him in the rotation by mid Summer. It's all spilled milk now............The way our rotation has fallen on it's face he might not have made a difference.
