Something else to consider... In 2018, he averaged 11.4 touches per game, and that includes all the games after the 5-0 start where he was either playing hurt or had to limit playing time. Through the first 5 games he averaged almost 13 touches per game. In 2019, he averaged 7.1 touches per game, which again includes the multiple games where he basically didn't play.
Also, 30% of his touches last year were carries, compared to 16.5% in 2018. While this versatility is a big part of his value, no NFL team is going to give him an overall workload like that, let alone that many carries, almost all of which were in between the tackles.
