True but he should be able to out perform the other team's scheme.
I hope that he returns and that our line improves. Adding a good run blocking tackle like Doyg Free could do wonders for all of our RBs. Bush would especially benefit as he has the speed and agility to get to the edge quickly and maneuver in space.
Right now what he needs more than money is success. Part of that is being on a winning team but the other part is production.
I wonder what his sponsors think of him changing teams. That could also be part of the equation.
