Tisdale, who visited nearby Champaign on Friday night for Illinois game, also received interest from Purdue and Southern Illinois.
``I always liked Illinois," Tisdale. "My family's always liked Illinois. The coaches are really good, the academics are really good. I figured it was the best choice."
Tisdale is a 205-pound junior whose defense is far ahead of the offensive end of his game. He's averaging 8 blocks to go along with 23 points and 10.5 rebounds per game this season.
``It was a little surprising," Tisdale said of the offer. "I was hoping it was going to happen, but I was relieved. I was a little nervous and when they got a commitment from Bill Cole, I wasn't sure if I'd fit in."
However, the Illini did a nice job of explaining the differences in the games of the two in-state big men.
``He told me how we could compliment one another," Tisdale said. "We play different positions."
