The usual WNY thin skin and rabbit ears.
Maybe Watkins hated the place and he has every right to hate Rex for pushing him onto the field (I know, people here will argue otherwise) last year when he wasn't ready, but I don't remember him ever bad-mouthing Buffalo. I agree with posters who say he's talking about coming back from injury and not taking a parting shot at the people who just sent him to a better situation (being in LA, not being on the Rams).
