That one seems pretty obvious.
We have 6 RB's, only 2 will get the bulk of the carries, with a 3rd RB maybe getting less than 100 carries.
No inside info, but my guess is CWH probably moves & possibly whoever loses out on the RB3 battle between Pringle, Lyle & Mallory could consider leaving as well.
With the new 5 to play 5 rule, if you're spending multiple seasons on the bench at RB, it's quite literally affecting your draft trajectory & earning potentiality. So, I would imagine RB's aren't going to be as patient as they may have been in the past.
