Jones being durable for 5 years should actually be a red flag. This isn't MLB, it's the NFL, all running backs are injury prone. That is about the dumbest thing I have ever read. All RB's are injury prone because they are all the same. Right. No, they're all injury prone because they have 11 200-350 pound men trying to hit them as hard as they can every [expletive] play. I understand your logic but it is well not logical. Sure RB's have a higher instance of injuries but to say like you did that Jones and Charles will not stay healthy simply because they are RB's makes no sense. A majority of RB's stay healthy. People are different. Reggie Bush is Reggie Bush and not Thomas Jones or anyone else. If someone has a track record of being healthy they are generally going to remain healthy.
