The best argument I think I’ve heard is to just drop football entirely and adopt rugby, a game similar enough to football that if you know the basics of football you’ll pretty much immediately be able to watch it, and, as far as I know, it has nowhere near the problems with brain injuries. The rationale I’ve heard from the latter is that rugby players don’t get to wear padding, and so there’s less proliferation of the sort of “here’s a 350 pound man running at 10 miles per hour, here’s a good 704 newtons for you” that football encourages.
