Redskins fans have cabin fever. The snow’s getting to them. No other team in town is good enough to distract local fans until NFL free agency begins March 17 and there’s not even a first-round pick for them to debate about.

Fans are flat out bored, so naturally talk turns to quarterbacks — trade Kirk Cousins for a first- or second-rounder.

Brother, if you’d trade a first-rounder for Cousins, there’s a house in Southern Maryland I’ll sell you for a million dollars. Don’t worry about no indoor plumbing. The walk from the penthouse to the outhouse, as Redskins fans learned last season, is short.

Cousins is going nowhere. Oh, he says he wouldn’t mind a trade (hint, hint), but he’s fine staying in Washington (wink, wink).

But the harsh truth was proven in late December when Cousins stumbled through three losses as Robert Griffin III’s insurance policy. There was nothing that showed Cousins is worth anything more than a pick in the fourth round — where he was taken in 2012.

The only way Cousins leaves is if some team goes nuts after the draft and offers a high 2015 pick after failing to get a passer. Teams make lousy trades, but not many are willing to overpay for a fourth-round backup.

Incoming coach Jay Gruden needs to see Cousins in minicamp before making any decisions. More likely, Gruden jettisons veteran third-stringer Rex Grossman, who’s no longer needed to mentor Griffin and Cousins.

But Gruden will learn Cousins is a valuable backup, which is needed given Griffin’s health history. Cousins and Griffin are exceptionally smart people who will quickly grasp the nuances of the new offense. Cousins won’t cause any problems off the field and supports Griffin on the field. That’s hard to find. And Cousins can come off the bench and quickly play his best like Gus Frerotte once did for the Redskins.

Washington won’t find Cousins’ replacement easily, so why trade him away unless someone overpays? It’s like selling your car to someone for $1,000 more than it’s worth only to realize replacing the vehicle will cost even more.

Fans are no longer talking about Cousins being a viable starter. He was a tease as a rookie when he led Washington to a late victory over Baltimore and a spot start triumph over Cleveland, but defenses hadn’t seen him before and the Redskins were on a seven-game roll.

Last year, Cousins was caught in the team’s nine-game slide. He threw four touchdowns, seven interceptions and posted a 58.4 rating. Frankly, Cousins is a younger version of Grossman with big plays and big mistakes. Nobody’s paying a high draft pick for that.
