The Utes have now signed six players, but forward Josh Hearlihy, who signed with coach Larry Krystkowiak in November, is expected to release his scholarship after telling California media outlets that Krystkowiak asked him to opt out of his letter of intent.
Without Hearlihy, the Utes still have three open scholarships for next season. Utah released six scholarship players from last year's team, which finished 6-25 and 11th in the Pac-12.
Taylor led Pacific Hills High School to a California state championship as a senior, while averaging 19.8 points, 7.5 assists and 3.8 rebounds per game.
"Brandon has a really good feel for the game of basketball," Krystkowiak said in a statement. "He is a tremendous shooter and a natural leader. He's a great floor general, with the ability to score and distribute the basketball. Brandon's teammates flock to him and love to play with him, and if there is one person on the floor who you want to have that quality, it's your point guard."
Taylor will compete immediately for playing time with junior Glen Dean, who gains eligibility after sitting out last season following his transfer from Eastern Washington, and fellow freshman Justin Seymour, a combo guard from Smyrna, Ga.
