I did the same thing back in May, because while I didn't expect Mac to be a league MVP, I didn't expect the complete other end of the spectrum. I was counting on him at least being as good as he was during his rookie year with Bill O'Brien in his corner and thought 10-11 games was possible. With that in mind, I figured, with this defense, they would have been adequate if they could have put up points and a few upsets could have seen things go their way.
Tom is far from "clueless" - hence the reason why he's as stunned as the rest of us that they're this horrific and he's not afraid to say it. I'm certainly far more clueless than he is, and I also didn't expect Mac to become a guy who has completely lost the ability to play the position. Yet, here we are.
