Wins is a fine stat to judge a team. But for pitchers it's really low on the list for me. If a guy like Rick Helling can get 20 wins with a 4.41 ERA and a 1.32 WHIP and Sheets gets 12 wins with a 2.70 era and a .985 WHIP there's something inherently wrong with the stat as a measuring stick. Like most stats, it has to be taken in context with other metrics.
