The impression I've gotten is that they like Oluokun so I don't think LB is high on their priority list. I also don't see why people think the Falcons are going to take a RB high. They have their stop gap and have a few players with potential behind him.
I'd like them to target someone like Delpit, Blacklock, or Madubuike but if they took Cushenberry, Jackson, or Hennessy in the 2nd then I wouldn't be surprised. It's not like Carpenter and Brown are reliable options at LG and they also desperately need an heir apparent to Mack, who has noticeably declined.
