Running back Trent Richardson was out of football last season. He has never averaged more than 3.6 yards per carry in an NFL season.

But Richardson has lofty goals in his comeback attempt with the Baltimore Ravens.

When asked by Comcast SportsNet how his story would end, Richardson said: "Putting on a yellow jacket."

Richardson, 25, is referring to the Pro Football Hall of Fame, unless he is planning to purchase a canary-colored blazer. This shows Richardson has the confidence. He just needs to show it on the field over the next few months, because he acknowledges this could be his last chance to make it in the NFL.

The No. 3 overall pick of the 2012 draft, Richardson is on his fourth team in four seasons. His career average is 3.3 yards per carry. He worked out for several teams before last year's regular season began, but no one signed him.

"As a person at that time, mentally [I] wasn't stable enough to play football, for any level," Richardson told Comcast SportsNet. "My mindset wasn't right for it. I had too much going on outside of football. The football was always there, but everything that carried on outside the field, it carried onto the field. I couldn't think about football all the time. Football became little to me at the time."

Richardson has battled injuries and his weight throughout his career. The Ravens didn't sign him until April because they wanted him to report in a certain condition, and he then missed the first full week of offseason practices with a hamstring injury.

He was back on the field this week as he looks to compete with Justin Forsett, Buck Allen, Lorenzo Taliaferro, Kenneth Dixon and Terrance West for a spot on the roster.

"This is a good chance of being my last ride when it comes to proving myself in the NFL," Richardson said. "I know myself that I'm not done in the NFL, don't want to be done. I got a taste of what that felt like. To tell my kids that their father didn't have a job, it was big for me. I'm here. I'm going to be here for a while."
