Peterson vaults to No. 1 on Big Board

Coming off an impressive showing at the NFL combine, LSU cornerback Patrick Peterson has jumped up to No. 1 on ESPN analyst Mel Kiper's latest Big Board of the top NFL draft prospects.

Peterson, weighing 219 pounds, ran a 4.34 in the 40-yard dash to go from a sure-fire top 10 pick to possibly one of the top two or three picks in the draft. Kiper thinks there's a chance that Peterson could go No. 1 overall.

Three of the top four guys on Kiper's latest Big Board, which reflects combine performances, are SEC players. Auburn defensive tackle Nick Fairley is No. 2, and Alabama defensive tackle Marcell Dareus No. 4.

In fact, seven of the top 13 players are from the SEC.

Georgia receiver A.J. Green is No. 6, Auburn quarterback Cam Newton No. 10, Alabama running back Mark Ingram No. 12 and Alabama receiver Julio Jones No. 13.

Peterson was among those players who gained ground at the combine, according to Kiper.

Among those who lost ground, according to Kiper, were Florida safety Ahmad Black and Newton. Black's best time in the 40 was a 4.74, and with him weighing in the 180-to-190-pound range, Kiper doesn't see that combination cutting it at safety in the NFL.
