When Canadian cruiserweight Ryan Rozicki, 20-1-1 (19 KOs), enters the ring on May 3 to challenge Badou Jack, 28-3-3 (17 KOs), Rozicki will be trying to tap into the spirit of the legendary Jack Dempsey.

Jack-Rozicki, for the WBC cruiserweight title, will be part of the card headlined by the super middleweight championship fight between Saul “Canelo” Alvarez and William Scull.

The 30-year-old Rozicki became obsessed with Dempsey as a teenager. Dempsey’s violent stoppage of the enormous Jess Willard on YouTube is ingrained in Rozicki’s head. Thanks to YouTube, a fight from over a century ago is an indelible boxing memory for the Canadian.
