You're not alone, no. I think the quality of many sports has gone down significantly. College football is nowhere near as good as it was when I was in college, neither is college basketball. NFL is still good but again the teams or skill level isn't as high, imo.
Part of it is just our generation getting old. I remember my freshman year in college, I asked a way older friend if he was watching the superbowl.and he told me that once I get older, it'll all be the same and will lose its meaning. He was right. I've seen thousands of games and fights...it's just all the same and nothing special now. Back in the day I wouldn't miss a big game for shyt and would plan my day around it...not so much anymore.
