Despite appearing to be on the decline at the time of the trade that brought him to Chicago, Cole Hamels has been phenomenal as a Cub. Since making his first start for the team last August, Hamels leads Cubs starters in both ERA and innings pitched. Kyle Hendricks has Hamels beat in some peripheral statistics, but you can certainly make a compelling case that Hamels has been the best starter on the team since he arrived.
