See dfwvarsity.com for results.“We're at their place this time,” Starnes said. “One thing you can say about those guys is that they are going to give you everything they have. We've got to be ready for a fight. We've got to be ready to go in there and battle through adversity, and we've got to win the game. But, that can be said about most of the rest of the games we have this year.”Grapevine lost to Colleyville Heritage 45-43 on Friday night, and Starnes said his team had some problems throughout the game.“I thought it was a great game to be a part of,” Starnes said. “They jumped out on us, and then we rallied back and had a seven-point lead on them going into the fourth quarter. Then they took a lead, and it was close all the way to the end. “We lost the game because there were things we could have done better. We struggled from the free throw line. We had turnovers and had missed defensive assignments, and to Colleyville's credit, they made us pay for those mistakes.”The Mustangs got back an injured Adam Sandy against Colleyville Heritage, who hit six three-point shots and scored 20 points in the game.Starnes said the objective at this point is pretty straightforward.“We just want to keep improving and showing up to work every day,” Starnes said. “We have to keep challenging ourselves and our opponents, and you never know what can happen. It seems like Trinity and MacArthur have pulled away from everyone, but there are three teams there with the same record, two games ahead of us and Colleyville. “With five games to go, anything can happen. We have got to find a way to execute better. We've got to get more balanced scoring, and we can be right there at the end. This is kind of a gut check time for us to see how bad we really want it.”• Over at Colleyville Heritage, the two-point victory over Grapevine improved their district mark to 3-6 as well and kept their playoff hopes alive.Noah Nelson led the Panthers in scoring with 11 points in the game, while Derrick Donnell and Brayden Miller each added nine points in the game.Markey Young, Jacob Sisk, Jackson Barlow and Wes Mong all combined for 16 points in the Grapevine game.Colleyville Heritage played Irving MacArthur on Tuesday night and will host Irving at 8 p.m. on Friday.
