Massive head trauma is the hallmark of modern-day contact sports.

Headgear might help but it does not seem to cut it.

Touch football is sensible because all tackling and smashing of humans against each other is avoided.

Maybe AFL, League and Union should be looked at for the introduction of minimal contact rules.

Players, clubs and leagues should have firm contracts in place – signed at the start of player careers and transferable with players moving from one club to another- that stipulate who will be responsible or liable for brain injuries associated with concussion, HIA and CTE developments occasioned by player impacts.
