Now over the course of any particular season, factors such as run support, bullpen effectiveness (more so in the past 30 years) and luck play a part one way or another. Runs support, bullpen, and luck play a HUGE role in a pitchers win/loss record. Why acknowledge that and and then say this: When your teams "ace" only wins 12 games Sheets had absolutely no control over his win total. A pitchers job is to let up as little runs as possible. Sheets did that, and he happened to do it very well. Unfortunately for him, the offense and bullpen didn't do well behind him. Why would someone still use wins to judge a pitcher when the stats flaws are so obvious?
