The Buffalo Bills are in a groove in the AFC East.

The Bills have won five-straight divisional titles. Buffalo runs the AFC East as things currently stand.

But it’s never easy to win a divisional crown in the NFL. If the Bills plan to do so again in 2025, these few things could make-or-break their upcoming season.

With that, here are three things that could make-or-break the Bills’ efforts at winning another AFC East title in 2025:

James Cook’s contract

James Cook provides a positive impact from the Bills’ backfield as his multiple Pro Bowl nods show.

However, Cook wants a new contract from his team. He has not landed one yet in Buffalo and he will be a free agent after next season.

If Cook doesn’t get that wrapped up soon, could it impact his production in 2025? Keeping opponents honest with a good rushing attack could be pivotal for the Bills and a contract distract might disrupt things.

The secondary

While Buffalo is used to having a strong secondary under the watch of head coach Sean McDermott, there are a lot of question marks currently there. Christian Benford is the clear top cornerback following his contract extension but there are other unknowns.

Will first-round rookie Maxwell Hairston find a way to be a productive starter across from Benford? Between Cole Bishop, Damar Hamlin and Taylor Rapp, who becomes a starter at safety?

Josh Allen’s health

It’s simple: The Bills go where Josh Allen takes them. If the franchise quarterback is hurt, it could end the season.
