is because of our frailties, our imperfections, and our physical limitations. We love talking about quarterbacks throwing 50 yards from their knees because so few can do that. Would we ever mention it if everyone could do that?
We love basketball because we have tall guys, fast guys, long guys. What if everyone were the same size? and the same super fast and could all jump the same, and have the same basketball knowledge.
and what about aging? We love college football and the NFL because someone is always getting too old making room for the next exciting talent. But what happens if no one ever ages out of sports like they do here? your teams would never change without some kind of rotation and since so many people would be interested, and good at sports, the number of potential teams is nearly exponential to what we have today. Oh you like the Zion Giants? Which one, I like Zion Giants team #460,972 cause my whole family plays for them. Mom's the QB and my sister is the center. Dad and I play defense.
What if every team made every shot they ever attempted? or every baseball pitch resulted in a home run? Or every football play resulted in no yardage gains. There'd eventually be parity everywhere and it'd be BORING. we want to see the exceptional happen and if everyone becomes exceptional, what's to see?
