"I like to compare the two to a quarterback and a lineman. Being a brakeman is very physical and success is mostly determined by how fast you can push a sled for about 30 meters. Your position is won or lost by the hundredths of seconds you are faster than another individual. It's like the lineman who is there mostly for their athleticism and physicality. The driver, like the quarterback, possesses a unique skill that takes a lot longer to learn."
