Chris Carson's usage should increase now that Carlos Hyde is in Jacksonville. With Seattle seeming to want to shift to a run-based offense, that's good news for Carson as the backfield will run through him. And you'll get production from him on a per-carry basis, as Carson averaged over 4.8 yards per carry in 2020. He's a solid RB2 with his usage in Seattle.
Carson did miss four games in 2020 due to injury and hadn't played a full 16-game season in his first four years in the league. Of course, now the season is 17 games, so it's certainly possible Carson will miss some time in 2021. Also, will he see more use in the passing game? Travis Homer is still around in that aspect.
2021 Bottom Line
Carson is very solidly in the RB2 range as a likely top-20 running back. He's going in the fourth round, near guys like David Montgomery and Josh Jacobs, among others. Seattle is also paying Carson $7 million a year, so they still expect plenty of production and have hopes for Carson going into 2021 in an ultra-competitive NFC West.
