Re: Are we overusing Foster?
I voted "Yes" because in the past 10-15 years, when backs get too many touches, they have a tendency to break down and not be very good after that -- CJ2ypc, Larry Johnson, Shaun Alexander, Ahman Green, etc.
So I'd prefer that Arian get around 300 carries and Ben get about 100-200 carries to evenly distribute the load and to prolong both of their careers.
Although... it's interesting that Arian's "idol" is Eric Dickerson. Dickerson was a HOSS. He had over 370 carries 4 times in his career and just kept on delivering. Granted, he only had about 6 good seasons before he was used up but still.
