It's when I hear people say stuff like "wins for a pitcher is overrated"..... that makes my head explode.
Cliff Lee's stats:
2012: 211 innings, 3.25 ERA, 207:28 K:BB ratio, 6 wins 3.60 Runs/game (run support)
2013: 207.2 innings, 2.95 ERA, 201:32 K:BB ratio, 14 wins 3.41 Runs/game (run support)
Two almost identical seasons with Cliff Lee actually receiving less run support in a season where he has 8 more wins. Wins as a stat are completely fluky and offer zero predictive value. Don't even get me started on a closer blowing a save in the 9th only for his team to come back and score in the 10th to get him the win.
Aside from saves, Pitcher wins are the most meaningless stat in sports. They weren't 50 years ago when pitchers were going for CG's every game, but the game is different today.
