The reason for that is smart GM's don't waste money on running backs.
Is 4-5 million dollars to upgrade to a top 5 RB room in the sport wasting money? I don’t think so.
I’d rather have Mike Evans, but to steal a line from a YouTuber, we need to stop saying “this is good enough” when chances to upgrade are on the table. Cook makes us a better team, if the salary is reasonable, it’s worth a serious inquiry if he’s ok being RB 2 getting 200 touches this season while Hall gets up to speed.
If he wants $8-$10 million, he’s not going to a contender, he’s going to a bottom feeder with cash, which won’t be us.
This of course all presumes that Cook get cut, because as you said no one wants that contract.
