With a total of 10 medals (two golds and seven bronzes), he is the only rider to have competed in at least one event in every X Games.

A co-founder of the Metal Mulisha, Deegan is one of the most recognizable names in action sports. First, he earned 10 XG medals in Moto X, then he made the transition to four wheels and has quickly garnered four more podiums. In 2010, Deegan surprised when he earned double silver in Racing and RallyCross. In 2011, he upgraded to RallyCross gold and then backed it up with bronze in 2012. Deegan attributes his success behind the wheel to his early days racing motocross and his success in short course racing. He's won the Pro 2 class of the LOORS series in 2011, 2012 and 2014 and finished 5th in 2018.
