Adrian Peterson is truly a no-risk acquisition for the Redskins.

The 33-year-old running back signed with the Redskins on Monday afternoon, for one year at the NFL minimum salary of $1.015 million according to Field Yates of ESPN.

The contract structure means that the Redskins can have him practice for the next week and a half, play in the two remaining preseason games, and then let him go prior to Week 1 and walk away owing him nothing.

If they do keep him for Week 1 against the Cardinals, his salary for the season will become guaranteed. But if they decide to let him go at some point in the season the payout of the remainder of his salary will be a drop in the bucket of a $176 million salary cap. There is no signing bonus, roster bonus, or other guaranteed salary.

One more team friendly aspect of this deal is that Peterson will cost less against the cap than the Redskins are paying him. The NFL has something called the veteran minimum benefit, designed to encourage teams to keep older players rather than the younger and cheaper one. Under this benefit, Peterson will count just $630,000 in cap space. That is the same cap charge as Byron Marshall carries. So, if it comes down to choosing between the Marshall and Peterson for a roster spot, the salary cap will not be a factor.

Apparently, Peterson is anxious to play football and after spending the entire offseason as a free agent who wasn’t drawing much interest, a player who received $11 million guaranteed from the Vikings two years ago will go to work for a fraction of that.
