TUSCALOOSA, Ala. (AP) -- Trent Richardson flashed speed and power at Alabama's second pro day.
The former Crimson Tide tailback, linebacker Courtney Upshaw and safety Mark Barron worked out for NFL scouts, general managers and coaches on Thursday. All three are projected first-round draft picks.
The 227-pound Richardson says he bench-pressed 225 pounds 25 times. NFL.com says he was unofficially clocked from 4.45-4.49 in the 40.
Richardson is considered the top running back available and a potential top 5 pick. He even knocked down Cleveland Browns running backs coach Gary Brown in a blocking drill.
The Browns, who have the fourth pick and need a tailback, were also represented by head coach Pat Shurmur and general manager Tom Heckert.
Richardson, Upshaw and Barron all were recovering from injuries at the NFL combine.
