Dill was a long shot to make the team, and clearly won't. Gibson would be the "project" the team keeps, so at some point, he's gone, so unless he gets someone hurts, who cares if he sucks
Even with that pick going for 2, I'd take Showers over Vaughn AND Weeden. He's made good decisions (but for that last pass), and he's athletic. He looks like someone to groom.
