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.

Andrew Luck had nothing to prove heading into his March 22 pro day at Stanford. But he went out and proved it anyway, completing 47 of 51 passes (three of the incompletions were drops) on a windy day in Palo Alto.
Luck opened and closed his throwing session with deep balls; the primary criticism of Luck -- and it's a slight one, mind you -- is that he doesn't have the arm strength to make all the throws at the NFL level.
"I think it was good," Luck said of the pro day experience. "It was a great opportunity to get out of here with some other draft-eligible guys and put a little showcase on."
Luck attempted 37 passes between 0-20 yards, and 14 passes of 20 yards or more, including a bomb to Chris Owusu that was apparently requested by a scout in the audience, and which traveled more than 70 yards in the air.
The most impressive thing about Luck's pro day, though, was his ability to spin the ball, with near-perfect rotation, through heavy California wind. Not that Luck was worried about it to begin with.
"No, I don't think there were any issues [with the wind]," Luck said. "It's something you play with. You can't tell the wind to stop if it's a Sunday or Saturday and you gotta go out there and play."
Additionally, quarterback guru George Whitfield chased Luck around in the pocket with a broom. While that sounds silly, Luck did make some impressive, into-the-wind, running-while-throwing-against-his-body throws that you might not see without the additional pressure.
"It wasn't perfect by any means," Luck said. "But I thought I completed some balls and showed some different types of drops and some different types of throws."
Also, in case you didn't know, there were a ton of media members present for Luck's pro day. It had to do mainly with him, but also because of the various talented players heading to the draft from Stanford's team. Which Luck won't hesitate to point out.
"I don't know if it's all to watch me -- I think we got a lot of good players on our team," Luck said afterwards. "It is what it is though. That's the state of the NFL culture right now, so you roll with it. Anytime Stanford's getting attention, anytime this program's getting attention, it's a good thing."
Kid's talented and humble. But he's also right: Coby Fleener, the top-ranked tight end by NFLDraftScout.com, did more for his stock than Luck. That's because Luck's already at the top of every board, and also because Fleener ran a 4.45 40. Not bad for a pass-catching tight end who's 6'6" and weighs 245 pounds.
Maybe the Colts should think about drafting him too.
