Jets linebacker C.J. Mosley was returning to a new environment back in the spring, even if he was with the same team.
Prior to his opt-out from the COVID-ridden 2020 season, Mosley briefly worked under an Adam Gase-led coaching staff that included a troubled defensive coordinator in Gregg Williams in 2019.
And then, following the opt-out, Mosley came back to Florham Park as a new head coach (Robert Saleh) and defensive coordinator (Jeff Ulbrich) were arriving. A new system was in place, new faces were in town, and a different type of energy was in the air.
