Casey was born in New Hampshire, but moved to Colorado at age five, and considers Denver his hometown. He played soccer at Denver's South High School and went on to play two years of college soccer for the University of Portland from 1999 to 2000. In his first year at the University of Portland, Casey was named best player of the year. In 2000, he led the NCAA in scoring with twenty-three goals and seven assists.
After playing well in the 2000 Summer Olympics Casey signed a four-year contract with German club Borussia Dortmund. After finishing a year of playing with the club, Casey was loaned out in the 2001–02 season to Hannover 96, where he scored seven goals in nineteen games. The subsequent year, Casey stayed with Dortmund, but only saw action in four games, scoring one goal. In 2003–04, he was again loaned to a second division club, Karlsruher SC, scoring fourteen goals in thirty games. In 2004, Casey signed with Bundesliga club Mainz 05, but scored only two goals and struggled with injuries during two-and-a-half seasons with the club.
After being released by Mainz, Casey returned to America and signed with Major League Soccer. Casey was originally allocated to Toronto FC  and after 2 games with 0 goals and 0 assists, he was traded to his hometown club, Colorado Rapids, on April 19, 2007, in exchange for Riley O'Neill and an undisclosed amount of allocation money.
He played 15 games with the Rapids in 2007, scoring 2 goals and 3 assists. In 2008, he scored 11 goals and 2 assists in 21 games. Casey ended the 2009 MLS season, with 16 goals, just one less than leader Jeff Cunningham to go along with 1 assist in 24 games. He was named in the MLS Best XI in 2009. In 2010, Casey became the All Time goal scorer for the Colorado Rapids as he scored 13 goals and 6 assists in 27 games. Likewise in 2010, Casey was selected as the MVP for the 2010 MLS Cup championship though the representative of the award sponsor announced "Casey Conor" when awarding it. In 2011, Casey suffered a season-ending Achilles tendon injury  in a July 16 game against the Seattle Sounders as he finished that season with 6 goals and 1 assist in 14 games. In 2012, Casey scored 2 goals and 3 assists in 18 games. On November 16, 2012, Casey was released by the Colorado Rapids.
On December 14, 2012, Casey was selected by Philadelphia Union in the first round of the 2012 MLS Re-Entry Draft, Stage 2. On January 23, 2015, it was announced that Casey had signed a new contract with the club for the 2015 season.
Casey played at the 2001 World Youth Championship in Argentina and then graduated to the senior United States national team, getting his first cap on March 31, 2004, against Poland. On July 7, 2005, Casey suffered a tear to his ACL while playing against Cuba in the U.S.'s opening game of the Gold Cup. He served as a late sub for the United States during several matches in the 2009 Confederations Cup. Casey scored twice (his first ever Senior team goals) against Honduras in a critical world cup qualifier at San Pedro Sula, Honduras, on October 10, 2009.
