Trent Richardson has yet to play a down for the Raiders -- his third team in a four-year NFL career.

However, the former third overall pick already feels more like the player who dominated in college at Alabama.

"I feel great," Richardson said in a BlabTV interview, via AL.com. "Not really a new beginning, but it's just a new start with everything. Got to leave Indy. You know how that trip went. That chapter of my life is closed, and I've opened up a new chapter. This offseason has been great for me. I got to sign a new deal in Oakland. I got to get my camp going again for the kids. I really got to get back in touch with myself and just got to get my faith back in myself and get back to doing the same stuff I used to do back in the day."

The Raiders inked Richardson to a two-year, $3.85 million deal with just $600,000 guaranteed in March.

Four years ago, Richardson's rookie deal with the Browns was worth more than $20 million in guaranteed money with a $13 million signing bonus. But in that time, the one-time Heisman Trophy finalist hasn't lived up to expectations. Richardson averaged just 3.6 yards per carry as a rookie, but he still managed 950 yards and 11 touchdowns in 15 games. His totals fell the next year, as did his average, and again in 2014, when he ran for 519 yards on 3.3 yards per carry and three touchdowns.

Richardson's weight was a problem in Indianapolis last season, when he was fined 14 times for being too heavy. Now, he said he's lost 14 pounds and is weighing in at 226. With that, he has a little more of something every athlete needs.

"Confidence -- that's all football is, any sport, anything you do in life," Richardson said. "You've got to have that confidence, that mindset. If you feel like you're overweight or you don't feel comfortable, you're out of it. There's no reason being in there. You're out of it."

Entering 2015 as a backup to Latavius Murray, Richardson will have to work for his carries. When they do come, though, he expects to look like the running back who ran for a school-record 1,679 yards and 21 touchdowns in 2011.

"People look back and say, 'Does he still have it?'" Richardson said. "I look at that and I smile. I think, 'You know what? I'll make sure that you know. I'll make sure that you know that I know that I still have what I used to have back in the day.'"
