Flynn. Neither will be good enough to trade for a pick. They're about the same age and price. Tolzien has a stronger arm but hasn't ever shown anything in a game. Flynn has proven he can win. If Rodgers goes down for a game or two, it won't matter either way. If he goes down for 8 games, I don't think it matters much either way if it's Flynn or Tolzien. I tend towards keeping Flynn, personally.
