Seems odd
O linemen are taking blows to the head 60 to 70 times every game
I totally agree with you. I was a pretty small kid, through elementary school I was usually the shortest and one of the skinniest kids in my class and usually smaller than most of the kids in the class behind mine. Usually once or twice a year someone would try to pick on me, which meant that once or twice a year I'd get into a fist fight because I absolutely refused to be picked on. I've never been in a fight with anyone smaller than myself and other than fights with my older sister and my best friend who was a year older than me I didn't lose fights.Being big has very little to do with fighting ability.
That reminds me of this. Who would win if these two went at it? A trained killer against one of the world's strongest men.
