In terms of a top-to-bottom effort from a team in the NFL, it’s hard to get much better than the effort the Buffalo Bills gave against the Miami Dolphins in Week 17.

When the Bills (13-3) put their starters in? Great work. Then when the Dolphins (10-6) took on Buffalo’s backups? They still were too much for the visitors to handle.

After looking at the tape and letting the dust settle, here are nine studs and three duds from the Bills in their win over the Dolphins:

Duds

RB Devin Singletary

Both Devin Singletary and Zack Moss only had three carries in this one. Moss had eight yards to Singletary’s seven. Neither guy had much of a workload, but Singletary usually has a promising catch or two. Instead, Moss turned heads in that role with an angry run early off a grab in the flat. Both will have more opportunities in the playoffs.

TE Dawson Knox

Dawson Knox had a nice catch late from Matt Barkley 20 yards down the field, but his effort came into question on a deep target on an early third down. In addition, Knox had eight targets throughout the game and only hauled in two of them. That’s not great for a guy who’s not exactly a touted blocker.

Sloppy starts

Slight bit of nervous energy there from the Bills in the first quarter, specifically on offense. Passes sailed, running plays went nowhere, balls were dropped, drives were not extended. Not a lot went right for the Bills in the opening quarter, as the team only gained 42 total yards and turned the ball over. Somehow, all whopping 56 points came after the first frame.

Push

CB Josh Norman

The veteran cornerback had a pick-six interception, Josh Norman’s first since 2015 when he was back with the Panthers. However, DeVante Parker finished with seven catches for 116 yards. Parker has a thing for solid games against the Bills, but about half of his grabs, slightly more even, came against Norman. Levi Wallace allowed his longest grab, though.

WR Andre Roberts

Andre Roberts is a deserved Pro Bowler. But he has one big problem as Buffalo’s return man: Roberts never scores. Isaiah McKenzie took backup snaps in the this role for Roberts and he scored the Bills’ first punt return touchdown since 2014. Funny how things work like that sometimes.
