You’re generally right but the OL play was subpar much of the game. Watch some of the rewind and you’ll see.
According to film review from NESN (Zack Cox, I think) ...
-----------------------------------------
PASS PROTECTION
RT LaAdrian Waddle: sack, three hurries
LG Joe Thuney: QB hit, three hurries
LT Trent Brown: three hurries
RB Rex Burkhead: sack
RG Shaq Mason: QB hit
C David Andrews: hurry
TE Rob Gronkowski: hurry
FB James Develin: hurry
— Among players who were in on pass protection, only running back James White came out clean.
— Waddle gave up the strip sack to Dante Fowler Jr.
— Burkhead gave up a sack to slot cornerback D.J. Hayden in the fourth quarter.
------------------------------------------------
Sony Michel actually came out "clean", too. He had at least one solid pass-pro block that I saw (I think). In any case, it makes me wonder if Burkhead's "disappearance" for the 2nd & 3rd quarters may have had something to do with pass-pro.
