Former Washington Redskins wide receiver Santana Moss said in a radio interview this week that Robert Griffin III went around bragging about being the reason Mike Shanahan got fired, and RG3 wasted no time firing back. On Tuesday morning, Griffin addressed Moss’s comments on Twitter and said his former teammate “openly” lied. It was common knowledge that Griffin’s relationship with Shanahan ended on a sour note, and Moss said he believes Shanahan was robbed of what could have been some more good years with the Redskins. The ex-receiver claimed Griffin essentially went around gloating that Shanahan got fired because he chose to bench RG3, which is likely the part that angered Griffin.
