Here's their offense heading into 2021:QB - Mac Jones, Jarrett StidhamRB - Damien Harris, James WhiteWR - Nelson Agholor, Jakobi Myers, N'keal Harry, Kendrick Bourne, Matthew Slater, Gunner OlszewskiTE - Hunter Henry, Jonnu SmithOL - Isaiah Wynn, Trent Brown, Shaq Mason, David Andrews, Mike Onwenu, Justin Herron, Marcus Martin, Ted Karras, Yasir Durant.Patriots defenseThe Patriots had a 4-3 defense in 2020, led my defensive coordinator Matt Patricia.
