People don't understand that Jordan wasn't the great athlete people claimed coming out of Oregon. He's a good athlete, but he doesn't have tools to win at a high rate in the NFL. He's fast, and he has solid agility, but when you're looking for a guy who is going to get you 10+ sacks (hello #3 overall), you need elite explosion or elite agility. Jordan has neither. I think he'll retire as a role player who was never became anything more than a role player.
Both Miller and Irvin posted 6.70 3-Cones. That's elite.
Jordan posted a 7.02 3-Cone. That's good if you're elite in another area, but Jordan isn't. So you have a guy who can move well and get around the football field, but you don't have a guy with the burst or quickness to WIN against NFL OT's, and that's what you need out of a #3 overall pick. Obviously, he's not going to cover or move through space as well as Miller or Irvin either.
