Its not just playoff basketball that will be on display Friday, when the Class 4A Region II basketball tournament tips at Cullwell Center in Garland, but more a celebration of tradition-rich programs.Among the four teams, Dallas Kimball, Mansfield Summit, Lancaster and Dallas South Oak Cliff, three have reached the state tournament a total of 26 times since 1960. While other regionals are not quite as celebrated, a tradition of success goes without saying. At the 4A Region I event in Snyder, Amarillo is going for its sixth trip to Austin in hopes of adding another title to the one the Sandies won in 1986. And Crowley is trying to return to Austin for the first time since 1999, the only time the Eagles took home a state championship.The competition is also tough in Class 5A and 3A.Class 5A Region I semifinalsat Daniel-Meyer Coliseum Lubbock Coronado (25-6) vs. DeSoto (29-3), 6 p.m. Friday Arlington Bowie (27-5) vs. Hebron (26-7), 7:30 p.m. Friday Final: noon SaturdayBowie, the District 3-5A runner-up, is the only 3-5A team to get past the first round.
