The Detroit Lions made a move to trade back into the second round of the 2011 NFL Draft to pick Illinois running back Mikel Leshoure with the 57th overall pick. Detroit didn't have any second-round selections before this trade, so they had to give up quite a bit to move up to pick No. 57 to take Leshoure.
Here are the details of the trade, which was made with the Seattle Seahawks (also known as Martin Mayhew's favorite trade partner):
Second-round pick (57th overall)
Third-round pick (75th overall)
Fourth-round pick (107th overall)
Fifth- and seventh-round picks
To sum it up, the Lions gave up their picks in the next two rounds and moved back in the fifth and seventh rounds to complete this trade. That's an awful lot to give up for Leshoure, but they obviously felt it was important to add him as a complement to Jahvid Best, giving the Lions a one-two punch at running back.
