The New England Patriots have added a 2020 option to Antonio Brown's contract that will pay him $20 million in guaranteed money if executed, according to Adam Schefter of ESPN.

The Patriots signed Brown to a one-year, $15 million deal ($9 million guaranteed) late last week after the Oakland Raiders released him.

What an offseason it has been for Brown.

Things began when the 31-year-old demanded a trade from the Pittsburgh Steelers at the end of the 2018 campaign. The Steelers met his demand in March, sending him to the Raiders for a third-round draft pick and a fifth-rounder.

But Brown proved to be more trouble than he was worth in the Bay.

The wide receiver missed most of training camp due to frostbite on his feet and a prolonged battle against the NFL concerning the usage of his now-banned helmet, a battle that featured Brown filing two grievances against the league, both of which were denied.

A boiling point was then reached last week when Brown was hit with a $54,000 fine from Oakland. Displeased over the penalty, Brown posted the fine letter the Raiders sent him on Instagram.

He then confronted Oakland general manager Mike Mayock in practice on Wednesday in a confrontation that nearly turned physical before linebacker Vontaze Burfict intervened and restrained Brown.

Brown apologized to his team last Friday and looked as if he would play in the season opener on Monday night, but he then requested a release from the Raiders on Instagram.

His wish was granted, and he then immediately signed with the Patriots.
