Devin McCourty: A-
McCourty gave up a couple of passes to tight ends while playing corner, but otherwise, he had another fantastic performance as the backstop for the Patriots defense. Tapping the ball to Marquice Cole instead of catching the ball out of bounds was the type of heady play we expect from McCourty.
McCourty is the top safety in the NFL, according to Pro Football Focus (subscription required) and did nothing to disprove that today.
Alfonzo Dennard: B
Dennard didn't have a shutdown type of day but didn't give up anything easy. Tannehill was held under five yards per attempt, and the strong tackling and tight coverage of Dennard played a big part of that.
Steve Gregory: B-
Gregory was the play-caller in the huddle, wearing the green dot on his helmet that Jerod Mayo used to wear. He only had one tackle on the day but was able to hurry Ryan Tannehill on a few blitzes.
Kyle Arrington: B-
Arrington, who was replaced by Marquice Cole again due to a recurring groin injury, had a nice pass deflection in the game. The Patriots need him—and Talib—healthy down the stretch.
Duron Harmon: B-
Harmon finished the game with an interception—which he technically should have batted down to save a ton of field position—and not much else. Gregory and McCourty were the main safeties Sunday.
Logan Ryan: A
Ryan made a huge impact against the Miami Dolphins, sacking Tannehill twice, causing one fumble and nearly intercepting him as well. This cornerback draft choice is turning out quite nicely for the Patriots.
Marquice Cole: B
Cole made an incredible interception and filled in nicely for Arrington again this week. While at his best on special teams, Cole has shown that he can contribute on defense as well.
