Robert Griffin III’s football career is a story of tragedy. While we’re not discounting a possible return to action by the former Washington Redskins quarterback, it’s unlikely that he’ll ever attain the greatness many believed he’d fulfill in the NFL.

Griffin is pinning much of the blame for the sudden decline of his stock to his coaches, particularly those who handled him during his days with the Redskins.

It’s well chronicled that Griffin and former Redskins head coach Mike Shanahan couldn’t get on the same page often and occasionally, the former Heisman Trophy winner would take swipes at Shanahan’s successor, Jay Gruden, for subtly making moves to ease him away from Washington.

Griffin made this apparent in a series of Twitter posts he made on Monday.

Then, during an appearance on 106.7 The Fan's “Grant and Danny Show”, Griffin further explained that Shanahan and Gruden made it hard for him to excel at his position because they simply didn’t want him as their extension on the field, per ESPN’s Josh Keim.

“I was drafted to a team with a coach who didn't want me, with an organization that wasn't sold on me,” Griffin said. “When you make that many trades and trade that many picks, you don't do that for a guy that you're not sold on.”

When Griffin suffered an injury in 2015 that forced him to miss games, Gruden called on Kirk Cousins’ number and Griffin was never able to get the starting job back before getting released by the Redskins in 2016.

After being waived by Washington, Griffin hooked up with the Cleveland Browns for a two-year deal in 2016, but injuries prevented his career from taking off again, forcing the Browns to cut him last March.

Griffin is just 27-years-old, but a brittle body and a perceived attitude problem must be discouraging teams from contacting his agent.
