New England signed Butler as an undrafted free agent out of Vanderbilt in 2017, and he made the team following an impressive training camp and preseason. He’s since become a solid depth player along the defensive line for the last three seasons, playing in all 48 games while racking up 62 tackles and 11 sacks.

Butler had a career year in 2019 when he played 47 percent of New England’s defensive snaps. He rewarded the Patriots for that increase in playing time with six sacks (including a pair of two-sack games) and 26 combined tackles. He also defended five passes throughout the year.

In addition to playing in every regular season game since he joined the Patriots — including eight starts — he’s also appeared in all seven playoff games, accumulating two sacks, four QB hits and seven tackles.
