Fullbacks are a dying breed in the NFL these days. But the ones that are still thriving like Lorenzo Neal are badasses.
If not for that neck injury, I think Strong would've played another year or two. I love fullbacks and some of the great ones are largely reponsible for the success a lot of feature running backs have enjoyed in NFL history.
Lorenzo Neal, for example has blocked for the following 1,000 yards rushers that I know of:
LT
Corey Dillon
Eddie George
Dalton Hilliard
Not a bad list.
Moose Johnson blocking for Emmitt Smith comes to mind also.
