Davis and Dixie high schools are searching for new basketball coaches following the retirements of John Robison of the Darts and the Flyers' Bill Brown. Robison, head coach at Davis for five years, is retiring at age 41 after winning the Region 1 championship this season to devote more time to NFL officiating and to his family. Brown retires after putting the Flyers in the 3A tournament this year. He has also coached at Delta and North Summit.
