Mike Zimmer had a feeling early Sunday that something was wrong with his team.
Re-energized by their victory in Jacksonville, his Vikings players had performed well in practice all week as they prepared for the Indianapolis Colts. And the return of running back Adrian Peterson contributed to the lift in their spirits.
But as they warmed up for a game they couldn't afford to lose, the coach sensed that his players were lethargic, and he still has no idea why.
His premonition was confirmed at halftime, when he gazed upon his lifeless team in the locker room at U.S. Bank Stadium after they had sleepwalked through the first half and fallen behind by 27 points to the Colts. The Vikings did not wake up in the second half, ultimately losing 34-6.
"I don't think it was a lack of effort," Zimmer concluded Monday, after twice watching the tape of one of the most lopsided losses of his three-year tenure.
The Vikings defense allowed Colts quarterback Andrew Luck to complete 75 percent of his passes for 250 yards and two touchdowns, and Colts running back Frank Gore topped 100 rushing yards as the visitors hogged the ball.
A day later, Zimmer labeled it an "uncharacteristic" performance and said his defenders, who did not sack Luck once, were not "flying to the football like they normally do." He wondered aloud if he was maybe "overcoaching" them.
As for his offense, Zimmer said the Vikings "started off slow," which was an understatement considering they had as many turnovers (two) in the first half as first downs. The critical mistakes continued in the second half.
