Steelers RB DeAngelo Williams shows his motivation in the form of termination papers from the Panthers

Most would agree the Pittsburgh Steelers might have had the steal of free agency in 2015 when they signed running back DeAngelo Williams to a 2-year contract to help back up Le'Veon Bell. When Bell was lost for the season due to a knee injury, Williams was just shy of having 1,000 yards rushing despite not playing the entire season as the feature back.

Where does a player like Williams continue to find motivation after so many years in the league? How about from his termination papers when the Carolina Panthers decided to part ways with the veteran running back from Memphis?

Williams posted this picture for "Motivation Monday" on both his verified Twitter and Instagram pages:

I am driven from within, but walking by this every morning absolutely adds fuel to the fire! #MotivationMonday pic.twitter.com/SQu8SiaN4Y

Some might chuckle at the thought of Williams holding a grudge over his old team letting him go, but when a player spends as much time in one location as Williams did in Carolina, it is hard not to have hard feelings over how things ended.

Nonetheless, the Steelers now have Williams in the backfield, and the veteran back is looking to finally claim a Super Bowl ring of his own in 2016, as a member of the Pittsburgh Steelers.
