Santana Moss claims Robert Griffin III gloated about his role in the firing of Mike Shanahan.

Griffin denied Moss’s claim in a tweet on Tuesday and called his former teammate’s comments “a betrayal.”

“Come 2013, all of [a sudden] it’s a whole big dilemma in the locker room, in the meeting rooms, and just in our building, that, you know, the man, Mike Shanahan, and RG is not seeing eye to eye,” Moss said of the fractured relationship between Griffin and Shanahan in 2013. “You know, we don’t know. We’re players. We sit back and let things be done. That’s not something that I partake in, so it’s not nothing that I’m interested in. And before you know it, RG’s not playing. … I’m not sure if that was [Griffin’s] whole plan, but when the whole thing went about, we hear that Mike Shanahan’s not coming back the next year, then we hear the quarterback like, ‘Hey, mmhmm.’ Like basically saying that, ‘Hey, you got me out of here not playing last year the last few games, then that’s what happens. You get fired.’ You can’t do that. One thing I just shared with you, God don’t like ugly. The little credit that [Griffin] did take for saying, ‘They didn’t like what I was doing’ or ‘They benched me and not allowing me to play,’ that’s what happens.”

“No subtweeting needed,” Griffin tweeted on Tuesday. “Santana Moss, I treat you like a brother and have always had your back. To openly like about me is a betrayal … ”

Griffin also claimed that he was “put in an impossible situation” with a coach in Shanahan who never wanted him.
