Moss was dealing with a hamstring injury. We think Moss has the potential to be an RB2, but certainly has a lot in his way, especially QB Josh Allen who is the team's goal line back most of the time. The good news is Moss was out-snapping Singletary last year when both players were healthy and since the team traded up to get Moss in 2020, the feeling is that should continue in 2021. We think if Moss can get 65% of the snaps, he'll get to that RB2 value.

Matt Breida’s speed has been mentioned by coaches and teammates as the main asset that he brings to the team. But he’s proving that his receiving ability could be the best way to unleash that speed.

The story said the Bills threw the ball 63-percent of the time in early-down, neutral game-script situations a year ago. They’re going to throw the football a lot. So the most useful running back on this team might be the one who can consistently make big plays in the passing game. Moss has made a few of those plays, and so has Breida. Running backs can be tough to judge at this stage in camp, but Breida should get a chance to show what he can do in the preseason, the story went on to say.

A week ago, rookie running back Zack Moss fumbled in a key spot, gifting the 49ers the shortest of fields and an easy touchdown. Sean McDermott and his coaching staff swiftly limited Moss’ snaps and said afterward the running back needed to learn a lesson. Credit to the Bills for not extending that lesson into this game against the Steelers. If Moss is going to show growth, he needs to know the team has confidence in him. The Bills showed that on the final drive of the game when Moss carried the ball six times for 26 yards and two first downs on Buffalo’s seven-minute, 11-second drive to seal the win.

The story added Moss got a clear vote of confidence on that last drive. The Bills ran 11 plays before Allen’s two kneel-downs, and Moss touched the ball on six of them. Moss took 59 percent of the Bills’ offensive snaps to Singletary’s 40 percent. He also had 13 carries to Singletary’s seven. And 26 of Moss’ 43 rushing yards came on the final drive. The Bills trusted Moss to be their closer, and the rookie delivered, the story added.

First, Devin Singletary lost a fumble in the fourth quarter that nearly cost the Bills their hold on the game. And for the fourth straight game, Singletary received fewer snaps than Zach Moss did, but by the biggest margin yet. Moss out-snapped Singletary by 13 (38 to 25); of the 199 snaps in the three previous games, Moss had just 15 more snaps than Singletary’s total (108 to 93).

As the story said, Moss entered the game for the last four snaps of the Bills’ final touchdown drive, stayed on the field for the ensuing drive and, once Singletary fumbled, took the majority of the reps the rest of the way. Moss was on the field for 18 of the Bills’ final 22 offensive snaps. Singletary lacks the true explosiveness to turn a running crease into a big gain, while Moss can power through contact and gain additional yards, the author went on to say.

Overall, the Bills revived their run game Sunday. But at what cost? The Bills are at their best on offense when throwing the ball and making the attack run through Josh Allen, and it never seemed in sync Sunday. Allen never got on the same page with Stefon Diggs except for some forced short-yardage targets. Cole Beasley was essentially a non-factor other than his touchdown throw.

The author added you never want to take away the best part of your own offense, and that’s what the Bills appeared to do Sunday. The Bills can still be an impactful running team without having a balanced approach. The story also said it’s all about the timing of run calls and the effectiveness of them and the run game likely will not be the reason the Bills have success in the playoffs. While it's just the author's view and the Bills may see things different, it's perhaps something to keep in mind, especially if you're a Moss or Singletary owner.

Zack Moss has missed the Bills’ last two games, but seems to be trending in the right direction after practicing on a limited basis all last week.

Moss could be a go in Week 5. If so, it will cut into Singletary's snaps and workload so it's something to monitor.
