49ers Make Trent Williams Highest-Paid Offensive Lineman in NFL History

The Niners have locked up their anchor on the offensive line. 

According to ESPN, the San Francisco 49ers signed Trent Williams to a six-year, $138 million contract extension, the richest deal given to an offensive lineman in NFL history. 

It's safe to say the 49ers took care of the 32-year-old Williams, who received $55 million in guaranteed money.

And it was well worth it. Williams was his usual dominant self last season on the left block, recording a 91.9 PFF grade, which ranked No. 1 in the league at his position.

Williams also received interest from the Kansas City Chiefs and Chicago Bears, per ESPN.

After signing Williams, the 49ers weren't finished with fortifying their OL. They're also expected to sign veteran center Alex Mack, reports NFL Media.

The 35-year-old Mack had been very productive the last few seasons in Atlanta, where he recorded an 84.7 PFF grade, good for No. 3 at the center position over that timeframe.

What do Williams and Mack have in common? They both have played under Shanahan before. And that certainly pays off.
