Let's face the reality gang unless the Bills are able to pull off some miracle trade for a Luck, or Carr, or Rodgers, etc., etc., there are just now significant upgrades that will be available. It really come down to three options if they want to make a playoff run: 1) hoping like heck that Cardale Jones proves to be something--and everyone that knows something in the organization, does not seem to think that is going to happen soon; 2) taking a gamble and hope you get real real real lucky and get a Zac Prescott like player in the draft--the odds of that are lower than Jones developing; or 3) staying with Taylor and focus on improving the Defense--this is what I would do.
And all three are a long shot . . . but let's face the reality, there just are not any quality free agents out there to be had!
