I know the Seahawks like to split carries with the RB's, but that was with two legit starters
Zach Charbonnet and K9. Both of whom were 2nd round picks. When Charbonnet went down with a season ending injury, Holani didn't step in his place and take on the same amount of carries as Zach. Holani had only 5 carries the last two games, while K9 had 46 carries the last two games. Holani is a JAG. Emanuel Wilson I'm assuming will be RB2.
Price is an immediate starting caliber RB while the other RB's on the roster, except Charbonnet, are JAGs. I don't think the JAGs will be splitting a lot of carries with Price. When Charbonnet returns from his injury, maybe November, then Price will have to share a lot more carries. I think Price will get 70% - 75% of the carries until Charbonnet returns.
