Wrong, wrong, wrong. Look at who went to the DL for the Yankees. Two of the 5 pitchers were the older ones you were talking about, the other three are younger than 27 and do not have injury histories.
First of all, there is no way anyone could have seen this Pavano thing coming. While he may have had some injury troubles, to expect him to miss at least 2.5 years of his 4 year contract (Probably closer to 3.5 years when its said and done) would make you a liar. The other older one with injury history is Moose, but his hammy has never been a problem, he has problems with his back.
Between the other 3, they have 4 DL stints between them, plus I believe Rasner began the year on the DL so you could bump it up to 5 for 4 pitchers under 27 with no history. Wang injured his hammy before the season (26, no history), Karstens went on the DL twice already and he never had before. And Hughes is 20 years old, how are you going to think that he was going give out like that?
There is absolutely no way you can pin this on Cashman. I absolutely disagree with you 100% on on this one. We have used 10 starting pitchers in 1.5 months, that has never happened in the history of baseball, and it is not because our pitching staff is so incredibly old and injury prone. While 3 of them are, the rest are not and have had freak injuries.
