In the 2008 NFL draft, the Carolina Panthers picked up RB Jonathan Stewart in the first round. In July 2011, the Panthers signed RB DeAngelo Williams to the tune of five years, $43 million. Now they're adding even more running back depth.
Tolbert, 26, is a big running back at 5'9 and 247 pounds. He spent the first four years of his career in San Diego, with his best season coming in 2010 when he rushed for 735 yards and had 11 touchdowns. He caught 54 passes last season, so he offers some versatility.
This makes you wonder what Stewart's future in Carolina is. He's under contract for one more season, and it's hard to see the Panthers investing even more money into their running backs.
No word on how much Tolbert is being paid but it is probably a decent amount considering it's a four-year deal.
