Former Alabama RB Trent Richardson, a member of the Crimson Tide’s 2009 and 2011 BCS national championship teams, hasn’t had a great NFL career, to say the least.

Richardson hasn’t given up on his NFL dream yet, though. But, in what may be his last chance in the league, he’s off to a slow start. According to a report by Mark Inabinett of al.com, Baltimore Ravens coaches aren’t impressed with the former Heisman contender.

Richardson has been largely absent for the Ravens’ offseason practices as he deals with a hamstring injury. Coach John Harbaugh said in a press conference that conditioning (or a lack thereof) may be to blame for the running back’s struggles:

“Trent just needs to get healthy,” Harbaugh said. “I think the workload and the amount of work it takes to be a world-class-conditioned athlete is something that he’s working on right now, and that’s what he needs to understand and that’s where he needs to get himself. And when he gets himself there, he’s got talent. I’m very certain he’ll get there, and when he does, we’ll be able to evaluate him.”

That’s not exactly a ringing endorsement for a guy who is most likely on his last legs in the NFL. But disappointment has followed Richardson at every stop in his professional career.

After he was drafted No. 3 overall by the Cleveland Browns in the 2012 NFL Draft, Richardson has failed to impress. When the Indianapolis Colts traded a 2014 first-round pick for the college star, it was widely mocked as one of the worst trades in NFL history.

The Colts waived Richardson in March 2015, leading him to sign with the Oakland Raiders, who released him before the start of the season.

Though it’s unlikely that Richardson will be a major contributor for the Ravens in 2016, it’s possible he can carve out a spot as a backup to Justin Forsett.

As far as the conditioning concerns go, maybe Richardson should call up former Alabama teammate Eddie Lacy, who seems to have addressed his weight issues this offseason.
