Green with the fourth pick. The Cardinals were up, and according to Dave Birkett of the the Detroit Free Press, passed on at least one trade offer before taking cornerback Patrick Peterson out of LSU.In a story detailing how Lions GM Martin Mayhew is willing to make big trades, Birkett recalls the deal that never happened.In 2011, Mayhew tried to trade up from 13 to 5 to land Patrick Peterson, offering his first-, second- and fourth-round choices. Ultimately, the Arizona Cardinals wanted to stay put so they could take a player that’s now one of the best cornerbacks in the NFL.
