Before Sunday’s Redskins-Vikings game in Minnesota, ESPN’s Britt McHenry reported an unsavory anecdote about Robert Griffin’s teammates appearing to disrespect the quarterback late last week. Via ESPN.com:

When Griffin began addressing the media in the locker room on Friday for the first time since dislocating his left ankle in Week 2, about 15 teammates began shouting. It was so loud and distracting, the franchise quarterback — and reporters — had to leave the locker room so Griffin could speak someplace where he could be heard. That’s when the cheering got even more boisterous.

A source familiar with the incident told ESPN’s Britt McHenry that Griffin has “alienated himself” from the locker room.

Local reporters strongly disagreed with McHenry’s characterization of the incident — which also appeared multiple times during ESPN’s pregame programming — and Jay Gruden upped the rhetoric during his postgame news conference.

“I saw those,” the coach said when asked about the pregame reports. “It was an amateurish report. It was totally not true. And for anybody who reads that to believe that, they’re an amateur. Anybody who reports that’s an amateur. It’s totally false. And just something else that you have to deal with up here at a press conference, that Robert has to deal with, that the players have to deal with, that they’re going to write about and ask about.

“But we are in D.C., and it is Robert Griffin, and they’re always going to try to tear him down and tear us down for whatever reason,” Gruden went on. “But we’re going to stay united as a locker room, and that’s that. We’re not going to let anybody get to us. That’s some small-time reporter reporting fiction.”

ESPN’s Michael Wilbon, a longtime Post columnist, strongly backed McHenry on Twitter before Gruden spoke.

So, too, did Mike Freeman.

But much of the Washington press corps chimed in before the game to dispute the ESPN report.
