I've been a boxing fan most of my life thanks to my father watching boxing every week when I was young and "asking" me to join him. And was fortunate to grow up in what I consider to be the Golden Age of the sport. There were so many good fighters in all weight classes during this period and lots of TV coverage of all but the PPV /Closed Circuit stuff, usually championship events. Saw a lot of Saturday afternoon ABC Wide World fights.
Got to see Hearns in Detroit while stuck there on a long term project. Knocked out Rojas in 69 seconds. I was impressed. Also saw Smokin' Joe's last fight at the Amphitheater here in Chicago, a "draw" against Floyd"Jumbo" Cummings.
Now and then, I'll pull something up on the web and watch it. It is hard to find boxing aired now and a lot of what I do find, is marginal, with heavyweights that look like Butterbean and fade fast or just poor skills.
I do watch some MMA and enjoy it but still prefer the sweet science.
(Also watch some old school wrestling occasionally - Crusher, Bockwinkel, and the old AWA guys. Nothing like Mean Gene Okerlund interviewing Crusher and Bruiser about the next bums they are going to vanquish after training by running the shores of Lake Michigan with a keg on their shoulders
