It isn't a surprise considering they had two rookies on the left side of the line in left tackle Will Campbell and left guard Jared Wilson. Campbell wasn't perfect during the game and clearly had his struggles late, including allowing a near strip sack fumble and getting flagged for two false start penalties.
However, most of the pressures in the game were allowed by Wilson, per Pro Football Focus, via The Athletic's Chad Graff.
Campbell allowed four pressures in the game, while right tackle Morgan Moses allowed five and Wilson allowed six. Center Garrett Bradbury had the best day with zero pressures allowed in the game.
