It seems the Washington Redskins have a triangle of trouble. Quarterback Robert Griffin III supposedly can’t work with offensive coordinator Kyle Shanahan, who reportedly doesn’t want to work anymore for his father and head coach Mike Shanahan, who benched the passer.

No wonder the team is flaming out with six straight losses and is heading toward a 3-13 season.

The Redskins aren’t just a passing team, they’re passive-aggressive. There are more leaks springing from Redskins Park than the Nixon White House.

It’s bad enough the Redskins have fumbled away another season, but the staff have been epic failures as leaders. And owner Dan Snyder is trying to figure out how to fire them without paying a $13 million severance.

Nearly every day members of the Redskins’ front office are using national reporters to paint their side of the story about this season — probably the Redskins’ worst since 1994.

And that shows exactly why Mike Shanahan needs to leave after the season. Wielding absolute power has corrupted Shanahan and his staff absolutely. Now they’re turning on one another in the final days.

This is not how a professional organization is run. It’s how a clown car in a circus operates.

And this isn’t picking on Snyder, whose sin seems to be favoring his franchise quarterback. Oh my, the horror.

Griffin’s struggles this season aren’t the only reason the Redskins stink. It’s because the team melted down in every fashion, and the coaching staff couldn’t fix it.

The players were the ones who turned the ball over seven times in Sunday’s 27-26 loss to Atlanta, but the coaches were at fault for too often having the wrong schemes and personnel in place.

Special teams being a disaster every week is on the coaches not finding the right players to embrace playing on that unit. If starters are needed, so be it.

If the offensive line can’t protect the passer, coaches need to make the hard choice and play reserves.

As for the decision to go for a two-point conversion at the end of Sunday’s game, the coaches pushed too hard. The Redskins’ defense had just stoned the Falcons for several series and had the momentum. Everyone always wants to go for the win with a last-second two-pointer, but the smart move would have been to take the game into overtime.

But then, Shanahan has treated the final three weeks as disposable so why not risk the outcome on a play that has a 44 percent success rate? Who cares if they lose another game? Obviously not the coach, who doesn’t figure to return.

It’s time to end the drama. Come Bloody Monday, the Shanahan era should be history.
