Taking a bunch of hits during a season will slow a RB down as well. I've seen some NFL RB's say that sometimes it's Tuesday or Wednesday before they can even walk without pain during a season. There was a video of Jerome Bettis where he could barely get down his staircase a few days after a playoff game.
Not hard to lose a step during a season.
