Vikings quarterback Carson Wentz had perhaps the worst game any NFL quarterback has had this season in Monday night’s loss to the Bills. He didn’t sugarcoat it afterward.

“This one felt pretty terrible. I’m not going to lie,” Wentz said, via the Associated Press.

Wentz completed 8 of 25 passes for 81 yards, with no touchdowns and two interceptions against the Bills. His passer rating of 8.9 was the lowest for any quarterback in any game in which he threw more than three passes this season. Wentz said he knows the Vikings’ defense can win with competent quarterback play, and he did not provide that.

“To go kind of lay an egg, personally, the way I struggled early, especially with our defense playing as good as they’ve been all year, honestly,” Wentz said. “They did it again tonight, and we just didn’t help them out. I didn’t help them out. It’s hard to put my finger on the why.”

The Vikings need to put their finger on the how, as in how to fix their offense. Or else a great defense is going to waste.
