If he drops - I think it would be because teams are focused on offensive side of the ball or say a team like Panthers maybe prefers DB to DT. I highly doubt he falls - but if he did I would run in and make my pick quickly.
The 3 players at this point where I think I would run in and make the pick - Carter (not happening), Graham, and I think I've convinced myself Jeanty (that he is more LT or name your Top 3 RB talent than he is a Top 10 back). I don't feel as strongly on the LT prospects as they all have flaws - but I certainly would support the selection of either of them and understand if they did it.
Mason Graham might be a bit undersized, but he's high character, high motor, and looks like he is just a flat out monster inside (and getting that interior pass rush is game wrecking in the NFL these days).
