The Jacksonville Jaguars drafted Michigan's Denard Robinson with the second pick in the fifth round. Had they passed on him, the Detroit Lions were apparently planning to take him two picks later, at least that's what NFL.com's Ian Rapoport is reporting. Earlier in the day, the Lions denied that Robinson was going to be their guy in the fifth round, but Rapoport's report contradicts that.
With Robinson off the board, the Lions ended up trading down to the end of the fifth round. They got an extra sixth-round pick from the Seattle Seahawks in the deal, and they later addressed their need for a running back/slot receiver/returner by taking Notre Dame's Theo Riddick with that pick.
If this is true, then the Lions made a mistake by passing on Robinson with their compensatory pick at the end of the fourth round. They used that pick on South Carolina defensive end Devin Taylor, apparently because they thought Robinson would still be there when they went back on the clock five picks later. In hindsight, they probably should have reversed those two picks, although there's obviously no guarantee that Taylor would have still been there when the Lions went back on the clock.
In any case, this just goes to show how tough the draft can be at times. Robinson probably thought he was going to be staying in Michigan to play in the NFL, and the Lions probably thought they were going to get an explosive playmaker from just down the road. Instead, the Jaguars threw a wrench in those plans, and the Lions' risk to wait until the fifth round to take Robinson didn't pay off.
