The move saves Buffalo $6.3 million against the cap. NFL Network's Mike Garafolo reports it is possible the Bills and Williams reunite down the road, but Williams clearly thinks he can do better than whatever pay cut or restructure the Bills offered him before this move. Williams started 17 games for Buffalo last season, splitting his time between right tackle and right guard. 

The deal includes nearly $14 million guaranteed. Signed to a one-year prove-it deal following a poor stint with the Panthers last March, Williams emerged as a significant piece of Buffalo's upgraded o-line in 2020, grading as Pro Football Focus' No. 22 tackle among 136 qualifiers. It's the second major deal GM Brandon Beane has struck in the last 48 hours, additionally re-signing LB Matt Milano to a four-year extension. Buffalo will return both its starting tackles for this upcoming season.

It's yet another ex-Panther/Sean McDermott reunion. 27-year-old Williams started 12 games in Carolina last season but was a liability. He primarily played guard after years at tackle, though he did spend some time on the blindside. He will be versatile depth in Buffalo. 

Williams had been limited during offseason work after recovering from a torn MCL and dislocated patella. The Panthers were so confident in his ability to rebound, they even signed him to a one-year extension this offseason. Now that Williams is healthy, he's projected to regain his position as the team's starting right tackle.
