I prefer to show them some actual boxers, not the past! Like the Whyte - Joshua fight, or Wilder KO's someone. People are getting excited and then ask me: hey what happend with Joshua or Wilder for example. Ogh and my favourite thing is to show them a photo of Usyk with his uber hairstyle!!! Everyone is shitting in DA pants.
Classic boxing match- Leonard - Hearns Classic Brawl- Corrales - Castillo 1 or Gatti Ward 1 Below Average/boring boxing match in a big event (let down) Trinidad - DeLaHoya
If it were all about gaining a new fan, I would say wars known and unknown like Foreman - Lyle, Hagler - Hearns and Lewis - Klitschko.
