Well, as an (used to be) avid sports fan, and engaged in many sports, I find I too have lost interest. Even in my favorite teams. I find them to be not as exciting, boring, and I find the athletes not as athletic. Yes maybe they are faster than last generation, maybe better players on paper, but the excitement is gone.
Something has changed. I thought it was me. Just getting a little older realizing how stupid it is for a person to chase a ball, puck etc for 60 or 90 min, playing 15 or 20 min of the whole game and making 100 bazillion dollars.
But then I thought about it, and I think its more the players. More are egotistical, arrogant, and standing on a pedestal types, than before.
Here in EU, and as a football fan of Manu, I hear many retired players-world class players-saying how many of the new players would never make it in their time, don't have the dedication, desire and more importantly-heart-to have played with the greats. Even Christiano Ronaldo still playing at 39 has said he has noticed a change in the players.
This is not just in football, but hockey, North American football, Basketball etc. None of the main sports is the same. Not as exciting. Almost a fabricated excitement. Heck even UFC. I remember watching UFC 1-5 and man were they great. No weight classes, no padded gloves, minimal rules, no protective gear so to speak. Now its all classes, padding, rules, refs stopping this and that. Not that I am a fan of UFC anymore, but everything had changed.
