The Oakland Raiders have three first-round picks and may be in the market for a quarterback.

Jon Gruden says he's impressed with Kyler Murray, who could become the shortest quarterback in the NFL.

"I used to think that a lot, until I saw Drew Brees twice a year in Tampa, then I met Russell Wilson coming out of N.C. State, and now I’m watching this kid, Murray, coming out of Oklahoma and I'm putting away all the prototypes I once had," Gruden said. "I used to have a prototype for hand size, height, arm strength, all that stuff."
