John Shuster and Hardline Curling come into Beijing as defending champions because they had the stones to challenge tradition in the centuries-old sport of Curling.
In the mid 2010s Curling, both Hardline Curling and American Olympic medalist curler John Shuster were facing a huge challenge from the powers governing this centuries-old sport. Hardline had come up with a controversial and revolutionary sweeping pad and Shuster has been dropped by USA Curling. Their next moves would have lasting impacts on the game you'll see in February.
Both join host Lauren Shehadi to share their stories of early success, tumult and vindication in a time known as "broomgate".
