There comes a point when the player loses all risk to his selection. When the cost of a player just goes by the wayside. Jamon Meredith has hit that zone. If he was selected in the second round and missed due to a lack of strength or desire or what have you? It would be a bad pick.
But at this point? Getting a potential heir apparent at left tackle with the skill set that Meredith has shown? It's spectacular value. Because some of his weaknesses can be coached out. And he has shown he can be a ZBS guard. He'll either be out of football in 2012 or he will be a Pro Bowler by 2014.
But as a speculative play? Gold, Jerry! Gold!
