Then, you also have to take into account the endurance that is needed and the beatings they take add up. Also, there's the speed, agility, toughness, balance, body control, power, strength, coordination, explosiveness and such that is needed to play that position.
So you have to be one of the best athletes at your school in order to play running back in your team? Would you say like a 6-pack is required or just helpful, for high school football of course. Not sure how much body control is needed for RB, It's needed for WR that's for sure.
