College
Metzger played college men's indoor volleyball at UCLA as a setter, where he won three NCAA National championships under legendary coach Al Scates. He earned AVCAAll-American for three consecutive seasons, winning the 1996 NCAA MVP and William G. Morgan Award for most outstanding player. He was selected to the NCAA Championship All-Tournament Team in 1995 and 1996.[2][3] He graduated with a degree in environmental studies.[4]
Prior to qualifying for the 2004 Summer Olympics, Metzger spent time competing internationally with former long-time partner Kevin Wong. In 2001, with Wong as his partner, Metzger won his first two AVP events, in Santa Barbara and Manhattan Beach on consecutive weekends.[4] The pair won the 2001 FIVB event in Switzerland and the bronze medal at the Goodwill Games in Australia. Metzger and Wong also won in Portugal in 2002.
Metzger won a silver medal in Rio at the World Championships in 2003 with Dax Holdren.[4]
In 2005, Metzger teamed up with the 2004 Most Improved Player, Jake Gibb. The duo won both of their first two events together, becoming the third team since 1990 to accomplish that. They won in Belmar, then placed second in an FIVB Grand Slam event in Paris, logging the highest finish by an American team in 2005. The win in Manhattan Beach in 2005 made Gibb and Metzger the second team to win four domestic tournaments in a season since the turn of the century, and also marked the first time since the 2003 season opener that a number one-seeded team won an AVP open event.[4]
