you might be right about Ricky. 380 rushes is alot of work. Edge and TD both had nearly 400 carries the year before their knees went. I saw an article somewhere concerning runningbacks whose workloads increase significantly from one year to the next often breakdown the following year. Although Emmitt Smith had a span of about 6 years or so where he carried the ball almost 350 times per year and never got seriously hurt, plus he was playing on turf the whole time. So who knows.
