But football isn't as "hit this hole" simple as it used to be, and, generally speaking, a RBs vision is superior to a FBs.
If Gronk and McGahee stick around, they can develop that kind of Jones-Drew and Greg Jones chemistry of what each other likes and will do and succeed off of it, but sadly, that's become pretty rare in this day and age.
49ers are the best running team in football and they use a FB, but it is true that FB's are used less and less.
Broncos are having difficulties running the ball as of late...
