None of them are that far off their totals -

Worth pointing out total yards per game is actually in favor of QB 3. I feel like at this point it's getting easier to pick out exactly who they are based on some of the added context that goes with the per game, and since I'm not the OP I don't want to completely spoil things. But I do want to point out the first post is total numbers, not per game.
