You mentioned this. This is what you said. If you want to play with straw men of 'I worked a lot and didn't include information' and 'I meant more than I said', that is your business. I will deal with the actual word in type. You have specific mention of the 90s and 60-70s. I'm not sure why you have such angst that I then refer a time period you mentioned.
You specifically referenced a player from a time period that concussion information was poor at best. I responded to that. Let's focus on this one player and era since that was the one mentioned.
