This discussion is getting kind of silly. I think the rhetoric can be toned down a bit and wait to see what happens with Fat Sabby. Other pitchers have successfully adapted to pitching with less velocity, and we just don't know whether or not Sabathia will be able to. Time will tell, and all we can do is wait.
That said, an argument can be made for the fact that fatty's declining quickly thanks to the loss of velocity, but the argument can be made that we just won't know if he will or won't adjust until the sample is bigger. All we can do is wait.
