A really interesting article from SBNation. Goes into challenges the game of football will be facing over the coming years, and how it can change to survive both by making the game safer and more watchable. From possible rule changes to new approaches to technique and strategies. Also makes a great point that while targeting rules were implemented to address some concerns, more detailed (and confusing) litigation is not a long-term solution.
I thought it was especially interesting in the comparisons to Rugby, another high contact game that has significantly fewer cases of traumatic head injury.
This was also a great followup, going into the essential aspects that define the game beyond the high level of contact, and what attributes should be preserved when making changes.
