"The benefits outweigh the risk for 99.9% of players"

Does the data support that or did you make that up? This would be a more interesting discussion if it has some scientific substance.

It sounds like the data is unknown for the remaining 99.9%. In that case, no scientific conclusion should be drawn at all.

I still appreciate his johnvschmitt's initial comment because it's an anecdote about how football has benefited him.
