The Buffalo Bills continue their 2025 NFL season with a matchup against the New Orleans Saints at home at Highmark Stadium in Week 4.

While game plans, coaching, and strategy will play a part, but sometimes a big emphasis will sit with some individual players. In terms of the Bills offense, who could those be?

Here are three potential X-factors on the Bills (3-0) offense against the Saints (0-3) in Week 4:

No one wants to assume that the Bills offense will roll against the Saints, but there is a good possibility. If that is the case, Cook will be called upon early but also later on to kill the clock and game.

Brown is battling a calf injury and there is a good chance he faces Saints pass rusher Carl Granderson. He leads New Orleans’ defense with 3.5 so far this season so the Bills will need their right tackle to stop him.

Coleman could be matched up on the outside against Saints cornerback Kool-Aid McKinstry and safety Justin Reid over the top at safety. McKinstry is Pro Football Focus‘ 10th worst cornerback so far this season and Reid is not much better, PFF’s 12th worst safety in the NFL.
