In 22 seasons at Commerce (1993-99) and Euless Trinity (2000-14), Lineweaver posted a 257-43-2 mark (.851), with 17 district titles and 5 runnerup finishes. Record at Trinity was 176-29, including 43-12 in the playoffs. He led the Trojans to 6A state titles in 2005-07-09, reached the finals in 2010, and made 5 other trips to the semis or quarterfinals. He was 81-14-2 at Commerce, winning a 3A state title with a 16-0 team in 1999 and could have won a co-championship in '95 with an extra point but went for a two-point conversion late in a 21-20 loss to Sealy. Lineweaver also served as offensive coordinator for Southlake Carroll teams that won two titles and 72 straight regular-season games under Bob Ledbetter. Emphasis on team bonding at Trinity was manifested in pregame dances, the Haka and Sipi Tau, that saluted the Tongan heritage of several players and have become trademark of the program.
