While agree there is a zero percent chance DD gets fired, I do think it's fine for people who think he should be fired to express their opinions.
I've never been a DD fan, and I firmly disagree with 2 of his moves while being ambivalent over the Price signing. I can understand those who disagreed with his philosophy to get even more upset over the fact that the rationalization of his philosophy was that we'd be HIGHLY competitive for 3-5 years. The quick exit last year and the two blow-out losses this year has driven some of those to this point.
I am not for firing DD this winter. I think every GM deserves 5 years. If the GM is spending large and trading many prospects, I can see giving just a 3-4 year window. A plan like Ben's, I feel, deserved a 5 year window.
