Priddy played the setter position for the Pride and helped lead the team as a junior to the school's first state championship in 1995.

In 2001, Priddy led the team in kills (258) and digs (184), and was second on the team in blocks (41) and tied for third in service aces (14), participating in the Japan Tour, Volleyball World League, World Championship Qualifier, NORCECA Zone Championships, and the Jeep America's Cup.

Although battling an abdominal injury for much of the season, he still finished third on the team in kills (224) and fourth on the squad in service aces (17).

In 2005, he made his indoor season debut in Japan at the World Grand Champions Cup as the Team USA claimed the silver medal with a record of 4-1.

He played in each of the final four matches (eight out of 13 sets) and scored 27 points on 23 kills, two blocks and two service aces.

In 2008, Priddy was part of the team which won the gold medal in the 2008 Summer Olympics defeating Brazil in final.

After leaving Lokomotiv, in 2010–2012 Priddy played for Russian club VC Zenit-Kazan and then for Halkbank Ankara in Turkey (2012–2013).

He returned to play for European clubs only in January 2016, when he was called to replace injured Simone Parodi by Lube Cucine Civitanova.
