I am going off his past history of carries over the season. If he can do more great. Even if he can do 20 carries a game, he still wouldn't be my pick. To be worth this pick considering his inability to catch particularly well IMO he needs to be insanely good on the ground. Like practically Derrick Henry good. I have mentioned it before but for various reasons RBs who can't catch a lot and get big YPC constantly really limit their value.
IMO for an RB to have any really value there are a few metrics they need to pass... 6.67 Yards per touch. It is hard to hit that number unless you catch a lot and well as well run close or over 5YPA if not over. As for why that number. It has to do with getting 20 yards on average for 3 touches (staying relevant with variance per play as well as overcoming penalties which tend to happen on most drives.)
Also catching is also about staying relevant in the game, period. You will sometimes face DLs that beat yours or Ds good against the run that you just can't run against on the per attempt basis you want. Do you want your 38th overall pick to just have no value some games? I don't. Which is why the damage they can do with the ball in the air is so important. Not to mention being able to get enough yards overall that have a big enough per play average to be relevant means a lot of touches.
