it can vary. Brandon Jacobs from the giants is 6'4", the size of a linebacker, and Darren sproiles from the chargers is i think 5'5". i'd say most are about 5'9" or 5'10"
some can be up to even 7'5" tall or a little more.
running back,half back,tail back,
Well this question can be different for each running back in the NFL. But since the running back position does not need to be the strongest person on the team, I would have to say that the average NFL running back benches some where around at least one thousand pounds honestly, in my opinion, thats where they would need to be to get notist by a scout
The average running back in the NFL makes around .9-1.2 million a year in the NFL
it is a person in football that runs running plays.....
The career of the average back is less than 2.6 years.
