Are you arguing he was the same last year?
He averaged 4.3 YPC in 2020, and 4.8 YPC during his playoffs breakout.
Last season when he came back he averaged 2.5 YPC on 67 carries, a decent sample size. He did have that one nice 40 yard catch in their first playoff game. I'd say he was not the same.
I'm optimistic that Mo can contribute, especially since it will be an entire year of rehab, and he was not a guy who relied on his athleticism in the first place. But I'm still worried he will be ineffective. Hope I'm wrong.
