OG simply isn't a premium position though. Even if he is the best prospect in the draft - which I don't think he is - it doesn't mean that he's going to go in the top half of the 1st round.
Usually more skill positions go in the early rounds. But this class is severely lacking in top end talent at the skill position. Instead its just loaded with mid level prospects that will be available in the later rounds.
If Floyd, Milliner, Joeckel, Fisher, Lotulelei, Ansah, L Johnson, Jordan, or Mingo are gone. I'd rather see us take the impact that Warmack can make for years with Cam than taking a flier on a player like Patterson or Richardson.
