Firing Torre would be reactionary, short sighted, and it wouldn't solve the problem of the Yanks starting rotation. Hey, the Sox had an off year last year and seem to be back stronger this year. Same could be going on with the Yanks. Firing Torre doesn't fix anything. He's overusing his bullpen because he has to (outside of using Pettitte in relief in real games which he should stop doing).
He's gone after this year anyway, so why now? If the Yankees make the post season there is no way they are able to win the WS anyway. The pitching - team wide - is just not good enough.
I will say, as a Sox fan, not seeing Torre in NY would make the Yanks seem even weaker. Once he and Mo and Jeter and Stienbrenner are gone, I'll be a happy man.
