This is my logic. Living in Philly, I have seen the drop off levels between elite QB play (Wentz), marginal starter/ quality back up (Tyrod/Foles) and the unknown dregs that idiots call for because they think anything will be better (Peterman/Sudfeld).
Elite talent will mask deficiencies you didn't know you had. Losing that changes election from Super Bowl to "maybe we win a playoff game". Dropping from the next level to Peterman level goes from frustrating to "I might be physically I'll watching this."
Unless my fantasy of the Bills trading for Luck comes to pass, we should start Tyrod Week 1, draft a guy in Round 1, and see how the season takes us.
