Johnson has coached at national juco power Navarro, since 1993, including head coaching duties since '94. Under Johnson, Navarro has a reputation as a great developmental program for high school pitchers before moving on to four-year programs. Johnson also coaches the Coppell Copperheads in the Texas Collegiate League, where UT battery mates Preston Clark, Adrian Alaniz, Joseph Krebs and Randy Boone are playing this summer. Current Horns Krebs and Clay Van Hook played for Johnson at Navarro before coming to Texas.
Johnson was selected over several other candidates. Another leading candidate for the position was Cal State Fullerton pitching coach Ted Silva. Silva pitched for Garrido for three seasons at Fullerton (1993-95), including an 18-1 campaign in the Titans '95 championship season. He also pitched in the Texas Rangers organization for five years, spent a year playing professionally in Taiwan, and also coached for a year at the high school level.
