Other performances of note:

-After a subpar middle of the season, Burfict echoed his strong first three games as starter (+5.7 overall) with a strong final three regular season games (+4.5 overall).

-While Taylor Mays does not appear to have the confidence of his coaches, he's done well by the PFF graders: in his limited defensive snaps on the year (248 total), he's graded +4.6 overall (+3.1 run defense, +2.2 pass coverage). Bearing in mind, of course, that 22% of his snaps came in this game, versus the Raven's second- and third-stringers.

-Kevin Zeitler bounced back from an atrocious game against the Steelers with a solid +0.6 (+1.3 pass block) against the Ravens.

-Center concerns: in the past two games, Robinson and Cook have cumulatively graded -9.1.
