Why? Well, primarily because being a pessimist is stupid and counterproductive.
But, here are some enumerated reasons for optimism:
1) Year two of Dorsey in his job. Experience is valuable, and now he's going to have some more tools in the box. I'm really bullish on the tight ends especially.
2) we have Josh Allen. So long as that alien clone supersoldier is our QB, we have a chance to win.
3) Another year for Groot. Last year, the Frenchman had a sneaky 8 sack season, I see no plausible reason he can't build off it. I see at least 10 for Greg.
4) no Leslie Frazier. Thank heaven.
5) The pressure of expectation is shifted to lesser teams in the Jests and Miami. This team does better in that environment.
I could go on, but go bills
