Running back Jahvid Best hasn't been on an NFL roster since 2012, after spending three seasons with the Detroit Lions. But now he's in training for a different pursuit.
A first-round draft pick in 2010, Best's football career was derailed by concussions; he suffered four in three years, including two in his final year at Cal and two during the 2011 season. He hasn't played a snap since Week 6 of that season, against the San Francisco 49ers, when he had 110 yards from scrimmage but also suffered another concussion.
Now 27, Best was a California state champion in the 100 meters at Salesian High School, and finished second in the 200 meters in an impressive 20.
