NEP Offense is a bit of a mess ... Cam is not the same he was years past. His Arm/Shoulder may not be up to the task of slinging it 500x a season. He is not the same runner he was in the past. True that Covid took a toll on him in 2020. But at 31 yo (?), his style of play is not suited for his body anymore and I see his replacement already on the roster.
When Mac Jones takes over, he is considered a quality pocket passes, and only runner out of necessity. And the typical "balanced offense" of NEP, Run 52-55% is the norm. Damien Harris was running well for the his limited touches (8 weeks in a row of 11+ with > 10 pts/gm in 0.5 ppr -- only 5 rec). With another season under the NEP program and with Sony's 5th yr not picked up, I like Damien Harris to get > 220 touches and >1000 yards in 2021. TD are tough to predict, but 5-7 is reasonable. Not heavy on the receptions but 10-15 is my projection.
Giving up a future 2nd & 3rd is a good price IMO for a quality RB2
ETA: I put him right behind Miles Sander range (but think Philly Offense is a wreck)
