On Sunday, the Lions were in the middle of a heated battle against the Los Angeles Rams, who remain the No. 1 seed in the NFC. With the Lions leading 24-20 midway through the third quarter, their fortunes were turned upside down.

The coach pointed to the third quarter of the 41-34 loss to the Los Angeles Rams. Matthew Stafford led the Rams to 17 points while the Lions didn't score and a seven-point lead turned into a 10-point deficit.

Lions suffer devastating 41-34 loss to Rams. Dan Campbell's defense collapses as Jared Goff and Amon-Ra St. Brown can't overcome second-half stagnation.

Rams quarterback Matthew Stafford threw for 368 yards and two touchdowns, connecting with star wideout Puka Nacua nine times for 181 yards in the shootout victory. It was another ugly outing for the secondary as the season is officially on life support.

Backing Detroit is the way to go, according to the model. The Lions cover the 6-point spread in 58% of simulations, good for an "A" grade. Detroit wins in 46% of simulations to offer value as a plus-money underdog and the Under (55) hits in 59% of simulations.

The Lions allowing the Rams to score 20 unanswered points played significant part in their sixth loss of the season.
