The Vikings’ addition of quarterback Kirk Cousins comes with a surprising decision on the back end.

Minnesota has not released any of its other quarterbacks. Giving the Vikings four quarterbacks on their 53-man roster.

With Cousins on the team, Kyler Murray, Carson Wentz, and Max Brosmer remain. It’s amazing, frankly, that Wentz hasn’t been cut; Monday night’s performance shows that he should no longer be playing in the NFL. Or the UFL. Or the CFL. Or any organization that ends with “FL.”

It’s hard to imagine Wentz sticking around for long. The Vikings possibly have decided to keep Wentz for now, given that Murray still has a hamstring injury.

Regardless, the soft benching of Murray has now become a hard benching. And the hard benching of Wentz inevitably will become a pink slip.

They’re all in with Cousins. The longer he plays, the better chance the Vikings have to make it to the playoffs.

It starts on Sunday, despite coach Kevin O’Connell being coy about it. Cousins undoubtedly will play. That’s why he’s there.

Even if he’s not 100-percent ready, a less-than-prepared Cousins is better than the other options they have.
