Bills can win 5 games on their Oline and Shady alone. That said, the 6 games they will win will give them a good range to trade for whatever QB they want next year. They're thinking a year ahead and can't blame them.
Shady won't have a good year, mark it down. Folks don't realize how important Tyrod is in blocking the 8th man, they're not going to be the same without the run option. Their LT may need foot surgery that will basically keep him out for most of the year, and RT is a complete mess. Watkins was their only consistent deep threat, but he's no longer on the field. It's going to be a slog on offense, they won't hit the deep shots they did in the past, loaded box all game long. McCoy was one of the best backs against a stacked box last season, but that's because the Bills optioned the 8th defender with Tyrod, you had to stay home. I want to see how it plays out, probably the most interesting thing about the team this year.
