Colleyville Heritage and Grapevine have completed their non-district seasons. It’s been very challenging for each as they enjoy their bye week. District 6-5A play begins Sept. 27 when Grapevine (0-3) meets Hurst L.D. Bell and Colleyville Heritage (1-2) takes on Euless Trinity.Let’s take a step back and analyze what we know about each team:Panthers The good: As demoralizing as the first two games were against Duncanville and Denton Guyer, this team responded with a big-time performance on the road at Flower Mound and pummeled the Jaguars, 45-7. Senior quarterback Griffin Pickler threw a pair of touchdown passes. Special teams also came up with a couple of scores on punt and kickoff returns. • Junior running back Demarco Corbin may be the best player on this team. He’s as much a threat running the football as he is catching it. Mike Fuller wouldn’t mind seeing him set a receiving yardage record for running backs. Corbin already has eight scores through three games, including a 71-yard touchdown reception.• Jacob Sisk has turned into a pretty decent find on offense as he has made the transition from defense (he’s still playing defense). He’s been a great replacement for Brent Bofinger, who is out with a broken collar bone. The concerns: A healthy offensive line is going to be crucial keep the Panthers’ streak alive of making the playoffs in each of coach Mike Fuller’s seven years. They received a scare last week when center Awais Charaniya missed the Flower Mound game with a hip flexor issue. While he could have played, the idea of not having a healthy unit is unnerving just because the depth is an unknown.• This defense probably isn’t as bad as the 70 points and 644 yards it surrendered against Duncanville or as dominating as the seven points it allowed against Flower Mound. There just has to be some consistency. Fuller said the group did a better of flying around the football and making plays last week. Now, there’s a standard to aim for.Mustangs The good: Coach Dave Henigan went with Adam Sandy as his starting quarterback for the final non-district game against Sachse. The numbers were decent as Sandy threw for 156 yards and two touchdowns but also threw three interceptions. A couple of turnovers in the red zone wiped out scoring opportunities. But he liked the way Sandy Grew in the ballgame.• The Mustangs also have a true warrior in Austin Parker, who is averaging 11.9 yards per touch. Problem is that he has only 18 total touches. So the team has to find a way to get him even more involved. Of course, a lot of teams know that and will try to limit how much impact Parker can have in a game.• With this expected to be a tough season, Henigan believes he has his players invested and ready to compete. He believes this team is improving. The concerns: This team doesn’t have the size or the depth to make its presence felt down in and down out. Henigan acknowledges that. So each week this coaching staff has to keep emphasizing this to his team so it can stay solid and improve its pad level.• Turnovers are a real problem here. The Mustangs have committed 10, including seven interceptions. They have forced only three.• Sandy is the leading rusher for this team and that’s not a good thing. Henigan dearly wants to find someone who can take some of the wear off of him.
