Former Pro Bowl running back calling it quits at just 31

He had a good career for a 7th round draft pick.

When Justin Forsett entered the NFL as a seventh round draft choice in the 2008 NFL Draft, he wasn't "supposed" to become a Pro Bowl player with a lengthy resume. However, that is exactly what happened. The nine-year veteran accumulated more than 5,000 total yards in the NFL, highlighted by a 1,266-yard rushing performance for the Baltimore Ravens in 2014.

Now, though, Forsett is calling it a career at the age of 31 and he penned his retirement in his own words on Sports Spectrum.

It's time. I'm officially announcing my retirement from the game I love. It's been an amazing ride and I'm grateful for every moment. My career has brought so many great people into my life, and I asked some of them to join me in saying goodbye.

Against all odds, critics, and naysayers, I accomplished something great. Scouts measured my height and said I was too short. They measured my 40-yard dash and said I was too slow. They looked at my build and said I wouldn't last. But they couldn't measure my heart, my faith, and my perseverance.

Forsett spent his final campaign bouncing between three different teams and, given his size at 5'8 and 190 pounds, he does not profile as a player who would have been able to play well into his mid-30's. Still, this was an unlikely career that accomplished a great deal and Forsett seems to have a handle on the next step.
