Josh Allen and the Buffalo Bills gave it everything they had in Week 4 against the New England Patriots, but came up just short. While they had chances to take the game all the way up to the closing minutes, the Bills ended up falling to the Patriots by a final score of 16-10.

It was a heartbreaking loss for the Bills. Allen went down with an injury during the hard-fought battle.

Despite the loss, the Bills proved one thing to the rest of the NFL. They are a legitimate threat and they are not going to go anywhere. Finally, the Bills should be viewed as a team to be reckoned with.

Unfortunately, Allen will have to deal with being in the NFL's concussion protocol. Buffalo head coach Sean McDermott was not happy, stating very strongly that the kind of hit that Allen took has no place in football. Many agree with him and it simply adds to the drama for the next time these two teams face off against each other.

Buffalo had a chance on their final drive to come through with a shocking upset. Even without Allen, the Bills were able to move the football well with Matt Barkley taking over at quarterback. Then, on a third-and-nine play from the New England 39-yard-line, Barkley threw a game-ending interception.

No one will argue that this loss wasn't a major disappointment for the Bills. Even fewer will say that the Bills showed they are better than the Patriot. But, what the Bills did do, is send a message to Bill Belichick and company.

That message? Quite simply, the Patriots are not going to have a breeze this season in their attempt to win the AFC East division.

McDermott has changed the culture in Buffalo. The team now believes that they are good and are capable of competing with the cream of the crop in the NFL. New England had dominated all of their opponents up to this week, but the Bills were not going to allow that to continue.

Being able to give that kind of a scare to Tom Brady and the Patriots is a huge accomplishment for a team that was considered to be a pushover just a few short years ago. Buffalo even had to play without talented young running back Devin Singletary and Allen missed some time late in the game as well.

Expect to see the Bills take this loss in stride and use it as even more motivation. Buffalo is for real this season and they are going to be a fun team to watch grow over the next few years as well.
