Holden, a 6-foot-2 combo guard, also visited Virginia Tech and Seton Hall, and he had previously considered Baylor and Kansas.
"Frank Martin was honest and was able to communicate his plan to me," Holden said. "I heard all good things about him through the process, and his vision for me aligns with my personal goals. I enjoyed the visit and the guys. I feel it's the best fit for me."
Holden averaged 17.7 points and 4.2 assists last season for a Delaware team that went 7-23, and he earned second-team all-CAA honors. He announced his decision to transfer in early March and immediately became one of the most sought-after transfers.
Holden was the No. 2 available transfer in ESPN's rankings. He will have two years of eligibility after sitting out the 2016-17 season.
"This redshirt year will allow me to develop my weaknesses and improve my strengths that have made me successful up to this point," he said.
