In the 2002 X Games, Metzger won the Freestyle and Big Air events and got second place in Step Up, earning him an estimated $100,000 in three days.

On May 4, 2006, at 9:26, Metzger completed "The Impossible Jump", doing a world record backflip over the fountains in front of Caesars Palace, Las Vegas, seen live on ESPN.

Metzger has appeared numerous times on the Discovery Channel's extreme sport show Stunt Junkies.

In the last episode he appeared in, he was seriously injured; while attempting to execute a jump with a back-flip between two barges, he overshot the landing ramp and suffered a compression fracture of the L4 vertebra in his lower back.
