"The Super Bowl champion Green Bay Packers struggled to run the ball most of last season after starting running back Ryan Grant was lost to a broken ankle during the first game against the host Philadelphia Eagles.

The team got a boost from rookie James Starks during the playoffs, but Grant's explosiveness and ability to make one cut and get to daylight was clearly missed.

Grant, according to a source, has a $1 million roster bonus due on the 15th day of the new league year. Of course, with the players being locked out, the start of the new league year is unclear. Grant also has a total of $750,000 of per game roster bonuses ($46,875 per game active) and a $3.5 million base salary for 2011, the final year of his contract.

If Starks has proven one thing this early in his career, it's that he could handle a lot of work. He carried the ball 81 times over a four-game stretch all the way through the Super Bowl.

"I think James Starks has a tremendous future in Green Bay," Packers coach Mike McCarthy said during last month's NFL Scouting Combine.

But Starks didn't even play during his senior season at the University at Buffalo because of a shoulder injury. In fact, he didn't participate in training camp, missed all of the preseason and missed the first 13 games of the regular season."
