My cousin played O line for Missouri. He loves football and I love my cuz. He's a college ref and was NFL chain crew for the Rams. I can't talk to him about this. Total denial. He's even mad that parents are voting with their feet by not sending their children into Pop Warner leagues.
Of them, my brother and the two that played at the D3 school are still hardcore CFB and NFL fans but they do openly discuss the CTE issues and are not thrilled at the idea of their own children playing. My cousin who went to Clemson, though, is still a hardcore fan and is in total denial. Out of the four of them, he got the closest to going pro and I imagine that has something to do with it.
