Knowing what we now know: Would you/will you want your kids to play football?

That was a biased study though. The brains were donated by families who suspected CTE.

 

Curious about some info I couldn't find from those results.
A) did they confirm which positions are the most dangerous?
B) what time frame were those brains playing (I'm suspecting 70's/80's) and how long/many games did they play?
C) is there any reason to believe that the equipment and rule changes have had a positive effect?
D) IF there is a positive effect, how can the money be raised to get the safer equipment starting aven at peewee leagues? NFL easily has enough money for the latest and greatest, but I think a lot of colleges would even struggle in this department, never mind young kids or HS which is where I think they expect it starts, MS or HS.
