Munch . . . munch. Crunch . . . crunch. Gulp!

What’s that noise? That’s me, eating my words.

I’ll admit I was wrong when I predicted in my September 6 column that the Redskins would have a record of four wins and 12 losses this season.

How wrong? The Redskins already have seven wins, including the last four games. Their 31-28 overtime win over the Baltimore Ravens on Sunday was super exciting. The red-hot Redskins may even make the National Football League (NFL) playoffs!

It’s not the end of the world to be wrong or make a mistake. Everyone makes mistakes. Whenever you make a mistake, it’s best to admit it, then try to figure out why you made the mistake so you won’t do it again. Don’t waste time pretending you didn’t make the mistake. Too many people — from presidents to professional coaches to kids — do that.

Let’s take a look at why I was wrong about the Redskins.

●First, I didn’t think Robert Griffin III would be so good so soon.

I figured Griffin would make his share of mistakes, like most rookie quarterbacks. Boy, was I wrong. RGIII is tied for first place with Tom Brady in passer rating after 13 games. That means he is ahead of Peyton Manning and Aaron Rodgers. Griffin makes all his teammates better with his speed, pinpoint passes and tricky ball fakes.

●Second, I didn’t think the Redskins had a running back who could take the pressure off RGIII. Wrong again. Rookie Alfred Morris has been terrific. Morris has averaged almost 95 yards a game with his straight-ahead running style. And cheers for the offensive line for opening the holes for Morris.

●Another surprise is newcomer Kai Forbath, who has been a perfect 14-for-14 in kicking field goals since the Redskins signed him in early October. The Redskins got Forbath after Billy Cundiff missed a lot of field goals early in the season. But before the Redskins got Forbath, the Dallas Cowboys and Tampa Bay Buccaneers had released him.

●Finally, the Redskins have much more team spirit than in previous years. Everyone from Griffin to the last guy on the bench is playing hard and helping out.

Can the Redskins make the playoffs? With three games left to play, they have a good chance of beating the Cleveland Browns (record: five wins and eight losses) and Philadelphia Eagles (four wins, nine losses) even if Griffin, who hurt his knee against the Ravens, can’t play. Two more wins might set up a big game with the Cowboys (seven wins, six losses) at home on the last Sunday of the regular season.

Yes, the Redskins can definitely win the rest of their games and get into the playoffs.

But it’s not a sure thing. I’ve been wrong before. I admit it.
