Reggie Bush? A run through some numbers

The Arizona Cardinals' plan for upgrading at running back could include the Miami Dolphins' Reggie Bush, who is scheduled to become an unrestricted free agent Tuesday.

That is the word from Mike Garafolo of USA Today.

New coach Bruce Arians spelled out his vision for the position this way: "Can they run the football, do they have vision, patience? Second, can they pass protect on second down? Can they pass protect on third down when it really gets complicated? Will we throw to the backs? Yeah. But the receivers are the ones paid to catch it.”

The chart compares Bush's 2012 production to that of the Cardinals' primary runners. Injuries wiped out Arizona at the position. Injuries also limited the offensive line and quarterbacks. That was a horrible combination. Arizona will almost surely improve in its running game simply because it's unlikely so many things will go wrong again.

Beanie Wells and Ryan Williams are coming off injuries for a second consecutive year. Bush, who turns 29 later this month, has missed one game over the past two seasons. He missed 20 games over the previous four seasons.

Also from Arizona: The team announced Early Doucet's release. He had slipped on the depth chart last season and was scheduled to earn nearly $2 million in salary for 2013.
