The Oakland Raiders have reportedly agreed to a deal with former New England Patriots offensive tackle Trent Brown.

It's already been a busy offseason for the Raiders, as the team has started to revamp its roster by making several significant signings.

Of course, the first came in the trade deal for wide receiver Antonio Brown, and now it appears that general manager Mike Mayock and head coach Jon Gruden have made another huge move by landing an elite tackle.

But it isn't just any deal, as Trent Brown is set to become the highest paid offensive lineman in NFL history.

From ESPN's Adam Schefter:

Former Patriots’ OT Trent Brown intends to sign a four-year, $66 million contract that includes $36.75 million guaranteed with the Oakland Raiders, per source, making him highest paid OL in NFL history.

There were plenty of questions surrounding whether or not Mayock and Gruden would be able to lure top free agents to the Raiders, but those questions are already being answered in an emphatic way.

It's clear that the franchise has big plans for the future, and adding these two players will likely put a smile on the face of quarterback Derek Carr.

The Raiders still need to make other moves since there are lots of areas of improvement, but this is an excellent start.
