The Buffalo Bills will face their first real test of the 2019 NFL season in the New England Patriots in Week 4. It is safe to assume that wide receiver John Brown will be a big part of the game plan on offense in Week 4.

Brown's stellar start to the year has been one of the more pleasant surprises of the season thus far. Not only are the Bills one of the few remaining undefeated teams left, but he has shown plenty of promise for a potential resurgence in the 2019 campaign.

Buffalo signed John Brown to a three-year deal this offseason in an effort to shore up some much-needed depth in the receiving corps. He has managed to provide them with plenty of bang for their buck by emerging as a serious weapon for quarterback Josh Allen in the passing game.

The 29-year-old kicked off his Bills debut with a spectacular performance against the New York Jets in the season opener by registering seven catches for 123 yards and a touchdown. Although his numbers have since cooled off, his skill set as a deep threat makes him more than capable of taking the top off the defense.

Even head coach Bill Belichick shared some high praise for Brown's ability to make plays from anywhere on the field, not just on deep balls. As a result, he may very well see a healthy dosage of cornerback Stephon Gilmore along with the rest of this formidable Patriots defense.

Trying to enjoy solid production against New England is much easier said than done given the sheer dominance they have displayed on that side of the ball. They currently lead the league in every major defensive category, including points (5.7) and passing yards per game (162.3). Belichick is likely going to do what he can to put the ball in Allen's hands as often as possible and force him to make all the plays.

While the young quarterback has shown plenty of promise under center this season, he will certainly have his work cut out against a defense that has yet to have its weaknesses exposed. The onus will fall on Brown to continue serving as one of Allen's go-to weapons whenever they are in need of some momentum on offense.

Although the Bills may be 3-0, there is still plenty of speculation regarding whether or not they are a legitimate playoff contender. A win against the Patriots would be helping them make quite a statement for the rest of the league.
