I have noticed a lot of really good white RBs are injury prone. Luke Staley, Kyle Bell, Chance Kretschmer, and Jesse Lumsden are some good examples.
of the running backs you mentioned, Kyle Bell and Chance Kretschmer each only have suffered one injury of note during their respective careers: a major knee injury. so i'd not say either was injury prone. rather, they each had the misfortune of suffering a devastating single injury.
Staley, meanwhile, had several fluke injuries where bones were broken in bizarre fashion. you might say this was injury prone, but it isn't the usual manner in which the phrase is used.
Lumsden, i'd say, IS an example of the more common use of the expression. he seems to suffer a myriad of small, nagging injuries that come from routine play in football. hamstring issues, groin pulls, shoulder straings, etc. i WOULD say he is injury prone.
the other three i would just say were incredibly un-lucky. just my two cents, of course.
