'MNF' takeaways: Steelers blowout Dolphins to retake lead in AFC North

After spending the first seven games of the season primarily at cornerback, where he played his first nine seasons, reaching seven Pro Bowls and being named first-team All-Pro three times, Ramsey has lined up at free safety on the majority of his defensive snaps (68 percent) since Week 9, per Pro Football Focus data. 

He's been excellent in his amended role, and Ramsey's effort contributed mightily to a stout defensive effort on Monday.

Quote of the game: "We saw the good... and then it's backed up with that floater."

Tua Tagovailoa's final numbers don't do justice to how poorly the six-year veteran played in a must-win game for Miami. He finished 22-of-28 for 254 yards, two touchdowns and an interception, but left several plays on the field with poor decisions or athletic limitations.

He killed a promising early drive with an underthrown ball to wideout Jaylen Waddle that resulted in his league-leading 15th interception, one play after moving the chains with a first-down completion. The sequence prompted "MNF" play-by-play announcer Joe Buck to highlight Tagovailoa's frustrating inconsistencies, from throwing on-target one play to badly missing immediately after.

"We saw the good ... and then it's backed up with that floater," Buck observed.

Color commentator Troy Aikman dissected the play later, highlighting the lack of a receiving option in the flat, allowing Steelers corner Asante Samuel Jr. to drop back into coverage.

"Tua's gotta know that," Aikman said, putting the onus on Tagovailoa to make better decisions.

It was a common occurrence throughout the game, with the 2020 first-rounder holding on to the ball too long on sacks and being unable to make plays with his feet. He also had multiple other throws that could have been intercepted.

It wasn't a good look for Tagovailoa, who is no longer the answer in Miami. Instead, he's the Dolphins' biggest problem.
