On Friday, Russell, a 6-foot-4 combination guard, changed his mind, committing to Thad Matta and Ohio State.
"Something clicked to me last week," Russell told Scout.com. "I just felt like today was the day."
"The environment is off the chain," Russell said. "I went up there and it was nice. The coaches, I just built a great relationship with the coaching staff. I didn't feel like anybody recruited me as hard as them."
"I just felt like, why wait," Russell said.
Russell said his relationships with Thad Matta and assistant Jeff Boals played a role in his commitment.
"I kept in contact with them and they kept in contact with me," Russell said. "I'm just trusting myself in making this decision. I just felt like it's the right decision."
Russell took an unofficial visit to Ohio State last weekend.
"Me visiting the school gave me a better idea," he added. "I met the president. Just being in the environment and me knowing who I'd be playing with just clicked for them. "
With the addition of Russell, the Buckeyes now have commitments from three top 100 recruits. Russell is ranked No. 11 overall, while Keita Bates-Diop ranks No. 28 and Jae'Sean Tate checks in at No. 52.
Ohio State also holds a commitment from three-star center Dave Bell.
