Robert Griffin III leaves letter at locker

— -- Washington Redskins quarterback Robert Griffin III didn't talk to reporters Monday, instead letting Dr. Kent M. Keith speak for him via a letter left in his otherwise cleaned-out locker.

The letter, which quotes "The Paradoxical Commandments," written by Keith in 1968, appeared underneath a framed verse from Philippians 3:13 with a picture of a road under the headline "I can do all things."

Griffin's tenure with the Redskins is likely over after Washington's 35-18, wild-card defeat to the Green Bay Packers on Sunday. Before pregame warm-ups, the quarterback looped around the field and stopped often to sign autographs, pose for pictures and chat with well-wishers.

This season, Griffin generally has received high marks for his effort off the field. A lightning rod for controversy during his first three seasons, Griffin stayed in the background in 2015, inactive for 16 of his team's 17 games after losing his starting spot two games into the preseason.

The Redskins will need to cut Griffin or pay him the $16.2 million option they picked up for 2016. They have until March 9 to release him.

He had provided diminishing returns since leading the Redskins to the playoffs in his rookie season of 2012, with career totals of 8,097 yards, 40 touchdowns and 23 interceptions.
