In the middle of October, Mike Zimmer is looking for proof that his one-loss Vikings team is special.
That's what Sunday's 21-10 beatdown in Philadelphia did to the NFL's last unbeaten team. The Vikings' shortcomings on offense, which at one point against the Eagles accounted for more turnovers (four) than points (three), exposed them as a team with some potentially crippling flaws.
Even as Zimmer tries to pick up the pieces, the good will built during a five-game winning streak has dissolved as they prepare for the Chicago Bears next Monday night at Soldier Field.
"I do have faith in this football team and obviously, you know, faith is belief without proof," Zimmer said Monday. "Right now, I don't have any proof, so I have to have faith that we'll get it done. I think we will. But until we prove it, it's just throwing stuff against the wall.
"We're trying to figure out everything right now. This is a gut-check day."
Zimmer verbally sorted through the reasons for the letdown loss, stopping on many "uncharacteristic" and "dumb" mistakes, including penalties in the red zone, special teams woes and receivers not getting out of bounds to save clock near the end.
One issue has grown notoriously characteristic: keeping quarterback Sam Bradford upright. The Vikings' most glaring weakness should take priority as coaches convene this week inside Winter Park.
Jake Long, T.J. Clemmings and Jeremiah Sirles, the rotating trio at the injury-thinned tackle spots, were exposed against the Eagles. They were routinely beaten and responsible for all four strip-sacks on Bradford.
