Not to be a debbie downer: The Bills arrow is definitely up, and 8-10 wins in my eyes seems like a very realistic expectation. The Bills finally beat New England last year but let's not get too crazy here: New England is still elite, and looks poised for a 13 win season, even if Buffalo beats NE once again, I don't see the Bills having that 12-13 win look, at least in 2012. The Bills still have some holes, and need more experience together as a unit to take that leap to 12 wins or more.
But even having said this, I have not had this much genuine excitement for a Bills season in 15+ years.
