It's a regression & clearly shows that the on-field results have gotten worse. The Bills spent a fortune ($100 Million for Mario) on new talent in an attempt to improve our team. We could add all the talent we want because Nix & the whole coaching staff wouldn't know how to play them best or prepare them for in-game changes. Our schedule has also gotten easier, as well as most of our opponents talent levels have dropped and yet we still regressed. Add in the fact that we drafted a shiny new sports car (Spiller) & traded away Lynch, who's been quite productive for Seattle to date. Nix spent most of this draft / off-season money on defense & our defense is one of the worst in the NFL, which tells you how this season is going to turn out.
After reviewing the last few years of regular season play with some improvement and the regression this year, I'd say there's no fix for Nix.
