That 07 team was an absolute mess as far as talent goes, but they only went 7-9 because the Jets were TERRIBLE and the Dolphins were 1-15 that year. I'd stop giving him so much credit because those were 4 easy wins for the Bills. As far as their other wins that year go...Baltimore was a bad team, and they were the only team Miami beat that year, the Bengals were bad and the Bills haven't lost to them since the 88 AFC Championship, The Redskins win on the road was a good win but they just had lost Sean Taylor so their minds obviously weren't all on football that week.
As far as the 06 team goes, do you really want to give credit to a team that lost to the Lions during those years? Once again they beat up on the have nots of the NFL that year to get them to a respectable 7-9.
