In this episode of the History Slam, Sean Graham talks with Game of Stones Podcast co-host Scott Graham about the fine line between innovation and cheating in curling. They talk about which innovations were deemed to be in violation of the ‘Spirit of Curling’, why others weren’t as controversial, and general resistance to new technology. They also chat about how things went from controversial to commonplace, the evolution of sweeping in curling, and what the next big innovation in the sport might be.
