Gom, don't say stuff like he took over a World Series and led them to a third place finish. He took over the team in 1998. The third place finish is going to occur in 2008. Between those years he finished in first place every year up until last year, when he won the wild card.
As for the draft, I agree, Cashman has done poorly in the draft. But, in my opinion, he makes up for it in other areas.
Gom, I think your opinion is being skewed too much by the events of this year. Yes, he should have made the trade for Santana, but one very poor move (or lack thereof) does not make him a bad GM. After making the postseason every year, albeit with a huge payroll, I think he deserves some respect.
