Lions vs Seahawks, Dolphins vs Titans

For many casual football fans, it might be a frightening sight to see Mike Macdonald roaming the Seattle Seahawks sidelines rather than the gum-chewing, confident Pete Carroll.

Macdonald is the youngest head coach in the NFL at 37 years old and one of the few to hold a head coaching job who has no significant playing experience beyond high school.

And although he spent several years as a coordinator and assistant coach in the NFL and colleges, he was never the man in charge. Seattle hired him earlier this year from the Baltimore Ravens, where he served as defensive coordinator.

No one feels more heat in Nashville than error-prone Titans quarterback Will Levis.

He has thrown five interceptions in just 94 passes, for a 5.3% pick rate, third highest in the NFL, and Tennessee's team offense ranks 29th with 260.3 yards per game.

But as shaky as those numbers were, the 25-year-old QB, who graduated in the same high school class as Brock Purdy and Trevor Lawrence, arguably performed worse on the eye test.

In a 24-17 loss to the New York Jets on September 15, Levis caused a fumble with a ridiculous, improvised sideways kick deep in New York territory that resulted in a turnover.
