it's quit funny until you are the one that is out there doing it...i played with a guy in college that shattered his kidney in three big pieces in the first quarter recovering a fumble...HE PLAYED THE WHOLE FIRST HALF AND DIDN'T KNOW THIS....so you right we don't have knives or guns but SERIOUS damage can be done out there...this kid at half time was looked over and they rushed him to the hospital and he ended up losing his kidney and his football career was over...this kid didn't quit, he is that type of kid i want on my team. the kid that feels pain and has to be "slapped" to get going again...ya'll can have them, i went 2-8 with a bunch of those type of kids..we had a few i wish i could clone...this is a great thread i will say the only time i would expect my dog to let go is if they were drowning, but soon as they came up they should be swimming to the hog to catch again....maybe i just expect too much...catch without quitting
