At this point, there isn't anyone thats available that would "save our season" if Allen goes down. If anyone other than Josh Allen starts games for this team this season we are completely done anyway.
That being said I'd like to see someone else backing him up as Peterman does not belong on an NFL roster. Seriously, I would rather have Landry Jones, Paxton Lynch, Bill Paxton, Tom Landry, Tom Jones, or Becky Lynch on the team rather than Peterman.
