First, Carolina is NOT a 2 win team. They have won one game. They are the leader in the Luck sweepstakes and I'd be shocked if they gave it up.
Second, as far as the Bills go, this conversation is moot. They won't be picking number 1 or 2. I'm guessing the Bills will pick after Detroit, Cinci, Carolina, and maybe even one other team (AZ would be my guess). I wouldn't even be surprised if the Bills picked 7 with 4 wins on the season.
