Here's an interesting Rick Reilly piece musing on the morality of watching folks knock the crap out of each other on the football field, noting the former players who are now suffering from brain damage from knocking helmets for years.
I can remember (in a non CAT-scan way) old boxers being "punch-drunk" from being in the ring for too long, but we're finding that a lot of football players have brains of 80 year olds in their 30s and 40s; Brett Favre, Dan Marino target Mark Duper and Tony Dorsett were the latest folks to come forward with signs of CTE, although Favre's diagnosis is anecdotal at this point.
I've passed on boxing and MMA for the most part, largely on the premise that I don't care for the side of me that likes seeing one man (or increasingly these days,one woman) beat the stuffing out of another. Reilly poses the idea that football might be best put into that bucket as well-
This is the game I've spent 36 years glamorizing. These are the men I've spent five decades lionizing. And it turns out I was part of the problem. Howard Cosell stopped covering boxing when his conscience wouldn't allow it, and yet I go on. I'm addicted.
Food for thought, at least.
