I don't watch pro sports because I can't relate to it. It's not interesting. Now college and lower are really interesting. There are huge differences in the athletes and you can see it. Mistakes happen so you can compare perfection to imperfection. Coaches matter too. And everyone is having fun. Pro just kills it. If they are going to go pro I'd like to see them go all the way and allow super modified cyborg humans compete.
I don't know why this was moderated "off-topic", it's relevant, albeit a bit of an "end game" perspective... At some level, the "purity" of a sport comes into play, and this "technological" decision is directly tied to that. Right now, we have human beings playing sports and human beings coaching sports. We disallow unfair augmentation of players (i.e., performance-enhancing drugs), not only because it would become a race-to-the-bottom for player health, but also because it removes that sense of fairness we currently perceive by "limiting" the players to the gifts with which you were born.
If coaching introduced technology without limits, it'd end up like Wall Street: a massive technological arms race to compute the "right" outcome faster than the opponents, and humans would be eliminated from the picture. YMMV, but I'm not interested in watching a sporting contest like that.
