I will blame JRob if he doesn't work out. There's a time to take a chance on a guy like this, but I don't think that time was now. I don't hate the pick because of the upside, but it's super risky. I personally don't think the drop off from Farley to guys like Newsome, Samuel, or Robinson was all that significant.
I know no one wanted an OT in the 1st, but I don't think many people saw Darrisaw falling to our pick. Almost every mock I saw had him in the top 17. He is a very athletic and a mauler in the run game.
