When you pay for your ticket, you're paying for the entertainment, for watching the game on the field - win, lose or draw. Everyone there got everything they paid for.. Changing the "outcome" after the fact doesn't change the experience they contracted for in buying a ticket.
I'm good with 15 or so carries per game over those games by JK, provided that it's at a 7 ypc clip. Throw in a healthy dose of McCall and Teague as backups and change of pace, a few (just a few) QB runs, and then some decent passing, and we'll have ourselves an offense. Save his body for games when it's really needed.
... although I'll be more than happy with repeating the outcome from the last time this happened.
