I love this guy's work.He has a number of 'what-if ' videos which proposes the probable outcomes of ' what-if ' situations such as a prime Mike Tyson campaigning in the 70s. He also has an extensive library of very knowledgeable,entertaining videos detailing the history of heavyweight-boxing. The site is called the Boxing Encyclopedia,created by Charles Jackson. I highly recommend this site.A very serious rival to Rummy's Corner.
