Three things to know about the Jets

1. Lots of Bell

Even though much has been made of the progress in Sam Darnold's game as he enters his second professional season at quarterback for the Jets, it is anticipated that the focal point of New York's offense will be RB Le'Veon Bell.

To say that Bell has fresh legs would be an understatement coming off a 21-month layoff from real football. Jets head coach Adam Gase said Bell told him this week to "not hold back," meaning Bell wants a heavy workload on Sunday versus the Bills.

Jets head coach Adam Gase also plans to use tempo as a weapon with his offense, where they'll hurry up to the line for quick snaps on plays during certain series based on down and distance and location on the field.

2. Shorthanded at linebacker

The Jets' will be down two starters at the second level on defense. Starting ILB Avery Williamson was lost to a season-ending ACL injury was a major blow to their front seven. Five-year vet Neville Hewitt is expected to replace him in the lineup.

Meanwhile starting OLB Brandon Copeland will miss the first four games this season due to a PED suspension. Harvey Langi is expected to start in his absence.

3. A very green punt returner

Buffalo's punt coverage unit will be facing a very inexperienced punt returner on Sunday. Braxton Berrios, who was just picked up off waivers by the Jets after he was released by the Patriots, has been appointed New York's primary punt returner.

A sixth-round pick of New England in 2018, Berrios spent his rookie season on injured reserve. So Sunday's game will be the first regular season game of his NFL career.

Berrios did get some punt return work with New England in the preseason with five returns for 46 yards (9.1 avg.).
