I can always appreciate a documented argument.
So Keenum doesn't have the Favre-esque arm that can scare a defense to death at any time
in a game, but what he can do is to create some open receivers deep through a good play-
action game. That is how the Vikings had a good deep game. They ran and ran the ball, then
took the open shot. Keenum is good at play-action, so that is what he needs to do.
