Not sure I completely understand the agument being put forward by OP etc, but my thoughts:
The pinnacle of a sport not being a sport, is F1.
As a fan it's tough to watch them regulate themselves. Certian teams have full-on veto powers on rules, and certain teams get paid millions just to rock up, because history. It's carzily unfair to newer or lower budget teams. Is why Ferrai is always on the podium, things are constantly stacked in their favour.
Liberty Media now that it has taken over is making big strides towards fairness to all teams and reigning in the crazy costs the well of teams/manufactures can pump in. But there's a long way to go (2021 at the earliest for true team parity)
NRL lost me a while ago, mainly because players are just commodities for the most part, no aleigence, they see money elsewhere, they follow it.
Rugby Union on the other hand is much more fascinating a game to watch. Actual strategy goes on. League is for the most part just played tackle to tackle, kind of a one trick pony imo.
Tennis is good too imo. Mano a mano.
Don't mind the hawkeye stuff. Humans can get it wrong or blink at the wrong moment.
