MLB: Should Wins Be Considered a Stat? - Sabermetricians will tell you that when it comes to pitchers, winning isn't everything. Easy for them to say. http://sports.espn.go.com/insider/news/story?id=6284300

Wins seems to be a stat of attribution which we know becomes flawed since it's dependent on the performance of others. A stat that considers not losing might be compelling. Another could consider the delta between team outcomes and the partial contribution starters make to those outcomes - both positive and negative.
