I have a short, simple answer as to why the Yankees boards dont talk about it.
It's because if you compare him with the pile of steaming bovine excrement that has been Yankees pitching this season, he comes out smelling pretty good. He's been the LEAST disappointing thing and even though, yes, wins arent a great stat to judge by, most fans still look to the win-loss record as a thing to decide whether or not to hate a guy. Numbers or no, he is still 13-5 (13-6 after tonight) and when your team as late as July was four thousand games under .500 and had eleventh graders, blind men, and trees on the hill every third to fifth day, winning 13 of a pitchers starts looks damn good.
