Re: Are we overusing Foster?
Kubes trusts Arian so much that he gives Arian the option to sub himself in or out depending on how he (Arian) feels. At this point, I think the high number of snaps for Arian is because Arian wants to be in the game.
Personally, I think they need to police his snaps a lot more and keep him on the sidelines some but... back in the day Eric Dickerson had several 350+ carry seasons (including a 400+ carry season) and didn't break down like modern backs seem to. Hopefully Arian is a throwback.
