Don't start with "a lot" unless you're going to come in here with a realistic figure or have something to back it up with. I just got done with this conversation.
You assume that this isn't a double-edged sword. You think Manziel never cost Evans by trying to get greedy with his elusiveness? You think Evans never had to make overly difficult plays because Manziel made some terrible decisions?
No. That play is not the Johnny Football Factor. The Johnny Football Factor resulted in a terrible throw into the middle of a bunch of Arkansas defenders and forced his WR to fly in and make the play. That's the Mike Evans factor.
No one is about to argue right now that this is the "Matt Stafford Factor":
Mike Evans bailed Manziel out on that play just like Calvin did here. If anything, it only speaks more highly of Evans that he could turn such a horrifically bad throw and decision into a TD.
