Serious question...
There are so many injuries at the RB position year after year. Gore, Lynch, and AP are the only RBs I can think of from a recent era that have lasted through time at the top of the depth chart. It seems like other RBs fizzle due to injuries within 5 or so years. They might stick around as journeyman backups but they're largely irrelevant.
We're concerned that our rookie RB will get worn down within his rookie deal like most other RBs have gotten worn down. How did RBs like Bettis, Eddie George, Emmitt Smith, Martin, Edgerrin James, Fred Taylor, Faulk, Barber, and Dillon all last a decade or more as productive players across several contracts - all within roughly the same era (a heavy rushing era also)?
