He could easily be a 15 game winner. His season last year was derailed due to a HR/FB rate out of th enorm, a really low strand rate, and high BABIP. His xFIP the last 3 seasons: 4.57, 4.31, 4.48 which puts him about average. Put on teh right team an average pitcher ca get 15 wins. Heck on the Brewers Looper got 14 despite being below replacement level.
