The Detroit Lions took all the suspense out of the first pick in Saturday's NFL draft by signing quarterback Matthew Stafford to a six-year contract Friday night. But the Lions made a couple of surprising picks later in the day, drafting Brandon Pettigrew with the 20th pick and Louis Delmas with the 33rd.Pettigrew is a talented tight end from Oklahoma State who will be a good target for Stafford, but I'm not convnced he was the right pick at 20. I would have preferred a player like Florida wide receiver Percy Harvin or Illinois cornerback Vontae Davis.
