IMO Brown will still be the main back this year with White getting the short yardage and goaline work. Henry will back them both up. If White really shines he will take more carries away from the other two but I think we will see alot of situational work. Brown is still our best 3rd down back. He is really good at draws and runs well after catching the ball out of the backfield, he also is a real good pass blocker. Nash, Payton and the rookie will compete for a roster position and the one we keep will be deactive each game until we have an injury. One could make the practice squad. I have a feeling Nash has an edge right now for the last spot.
