Builders sign William Tisdale
Men's Basketball - Tue, Mar. 29, 2011
William Tisdale, a 6'2'' senior from Holland Hall High School in Tulsa, has signed a letter of intent to play basketball at Southwestern College.
SC Coach Matt O'Brien said Tisdale averaged 16 points and 9 rebounds per game in his senior season and was named a first-team all-conference player. He was also a McDonald's All-American nominee.
O'Brien said Tisdale, who plans to major in sports management, definitely has the pedigree to become an outstanding college player.
His father, William Sr., was a McDonald's All-American at Booker T. Washington High School in Tulsa and later played for the University of Oklahoma. His uncle, Wayman Tisdale, was a standout player for the Sooners and was the second overall selection in the 1985 NBA draft, in which he was selected by the Indiana Pacers.
"We are elated that William chose SC to further his education and continue playing basketball," O'Brien said."William has a great deal of ability and athleticism and a tremendous amount of upside. He fit right in with our players and was comfortable with Assistant Coach Gene Hartman early on in the recruiting process. I am excited to have him and his family become a part of our basketball program for the next four years."
