That's a big part of the problem... Pads are lighter, helmets are gettin' better... So the hits gets bigger... Bet fools WEREN'T gettin laid out like they do now with those 'leather' numbers Newt Rockne used to wear...
I just wish people were more aware of how bad a concussion can really be. When James Harrison says some shit like "basically he fell asleep for a little while and then he woke back up and he was OK", he shows a complete lack of knowledge about the long term effects of multiple concussions. If people knew, they'd be able to make better decisions about whether they wanted to take that risk or not.
