The Jazz began training camp on Friday and the addition of Reynolds gives them 17 players in camp, meaning the team will need to cut at least two players by the time the season begins.
Reynolds was playing in the Philippines before deciding to accept Utah's offer. He spent last season with the D-League's Springfield Armor, where he averaged 13.1 points and 5.9 assists.
During his time with the Armor, Reynolds worked on becoming more of a true point guard. He was known more as a scoring point guard during his time with Villanova.
The Jazz backcourt already holds veteran point guards Devin Harris, Earl Watson and recently-signed Jamaal Tinsley, so it's unclear what role Reynolds would play.
