Despite dealing with multiple injuries as well as the opt-out of starting right tackle Marcus Cannon, the New England Patriots fielded one of the best offensive lines in the NFL in 2020. The subsequent offseason still saw them make some changes, though: the team reacquired Trent Brown via trade and also moved on from Cannon; it also added William Sherman on the third day of the draft.
The Patriots entered the 2021 season with Isaiah Wynn and Trent Brown filling the two tackle spots. While Brown missed some time due to a calf injury, the duo was undisputed in its standing atop the position depth chart.
