LSU's Patrick Peterson, who some believe is the best player in the draft, ran the 40-yard dash in 4.32 and 4.37 seconds. That speed, along with is playmaking ability, puts him firmly in the top 5.
At 6'0" and 220 lbs., Peterson would be considered a big cornerback in the NFL. He also showed off his athleticism with 38-inch vertical jump and a 10'6" broad jump.
While Peterson is king of the cornerbacks, Nebraska's Prince Amukamara proved he's not a bad second option. Amukamara ran the 40-yard dash in 4.37 and 4.44 seconds. Speed was a question mark for Amukamara heading into the Combine, not anymore.
Amukamara is another big cornerback who can be physical with bigger NFL wide receivers.
