Know this about former Ball State quarterback Nate Davis: The man has an absolute cannon for an arm.
Having seen it up close back in 2008, when Davis threw the Cardinals to a 12-2 record, I can attest that there are few arms better right now in the NFL. Unfortunately, Davis' well-documented learning disability sunk him in San Francisco and Seattle.
Now he's apparently landed in Indianapolis as insurance behind Peyton Manning, who's still recovering from neck surgery.
I can't think of a better situation for him, given both his strengths and his drawbacks. He'll have the opportunity to learn from the most prolific (and maybe the smartest) quarterback in the game, while not being in a position where he's likely to thrust into a lot of game-on-the-line situations (or game situations, period). And from the Colts standpoint, they get, again, a restaurant-quality arm.
So win-win, it looks like from here.
