2013 NFL Draft: Cal wide receiver Keenan Allen ranked top underclassman WR heading into the draft

California Golden Bears wide receiver Keenan Allen, who has decided to declare for the draft after his junior season, in which he caught 61 passes for 737 yards and six touchdowns. NFL.com ranks Allen as the top underclassman wide receiver to declare for the draft, saying that he is a clear No. 1 receiver in the league and compared him physically to Braylon Edwards.

A smooth outside pass-catcher, Allen has height, speed and the ability to win jump balls, all traits that are required of a No. 1 target in the NFL.

The 6-foot-3, 206-pound receiver has the size to catch passes across the middle and the speed and athleticism to catch jump balls down field. With as many teams in the NFL that desperately need help at wide receiver, guys like Allen won't stay on the board for long.

The NFL does see a downside to Allen, which is his speed. While he does have the speed to challenge most cornerbacks, many analysts don't believe that Allen's speed is elite and that he may struggle to separate from some of the NFL's better cornerbacks. He has also struggled as a blocker at times as well.

ESPN ranks Allen as the second best wide receiver in this year's draft class after Tennessee's Justin Hunter, and is listed as a probably first-round draft pick. CBS Sports' Rob Rang has Allen going to the Dolphins in the first round of the 2013 NFL Draft at No. 15 overall.
