You know, it's counterintuitive, but I think that many of the injuries we now see in football, especially concussions, are a result of "better" equipment. We have faster and bigger player using more force (mass x acceleration) against each other and causing more injuries.
For anecdotal evidence, look at rugby players. They are just as "rough and tough" as footballers but their injuries are actually reduced because of less padding and equipment.
For instance, you protect your head with a stronger helmet and you feel that you can't be hurt thus taking chances. Do it once w/out a helmet and you've leaned.
Just a thought.
I think you're right.
Maybe giant people produced by steroids has a little bit to do with it. Maybe even just the steroids cause a lot of the long term damage.
Leaned? Does that mean that once you've been hit, the fat gets knocked out between the ears, and you can start thinking more clearly?
