If you can believe it, Colleyville Heritage will finish its spring football season on Friday with 13 practices.And new coach Darren Allman did it by stripping it all down to a basic version. Because other coaches could not get released from contracts, he has gone through the spring without a full staff. He’s had only four assistants consistently working with him. In order to know exactly what he has, Allman’s staff has spent one day working all 180 players on defense and turned around and worked them on offense the next. But Allman did not accept there was another alternative than to begin this program this way.“We’ve had to squeeze a lot in,” Allman said. “It’s like you almost have to plan on the fly because you don’t have a full staff with you. But I can’t imagine where we would be if we tried to get it started with the extra week in August and not go now. We would have been really behind.”Like Randy Jackson at Grapevine, all Allman is trying to do is implement his brand of football with his players so they have an idea of the expectations. Conversely, he and his staff are still getting to know the players. The sessions are broken into defense and offense because Allman wants to have an idea of who will be better suited for either side of the ball.“It’s really been about us just teaching them and getting them to understand how we practice and how we go about our daily work,” he said. “I’m sure there is some overload, but we’ve really tried to make sure there is a slow insertion.”Naming the staffAllman knows who will be on his staff. But as mentioned above, he just doesn’t have them all on campus yet and won’t until the summer.By his definition, he will have an offensive and defensive coordinator. However, each will have a co-offensive and co-defensive coordinator.On offense, Kris Boyd will be coming from Bandera, which is just northwest of San Antonio. Boyd is one of the coaches who cannot get released from his contract. The co-offensive coordinator is Justin Feaster, who was released from his contract at San Antonio East Central. Feaster will focus on the quarterbacks. The defensive coordinator is Judd Thrash, who has coached at Rockwall Heath and Round Rock Stony Point. The co-defensive coordinator is Ty Kuhn, whom Allman hired away from Temple to join him at Austin Westlake.The coaches who are helping in the spring are defensive line coach Lee Rabe, who can commute from Saginaw Chisholm Trail, and running backs coach Robbie Waters, who previously worked at Flower Mound Marcus.Who is where?Last Friday’s scrimmage was really the first time Allman could evaluate offense against defense. Allman is looking at four quarterbacks. The apparent leaders would be seniors Clayton Oliver and Trevor Anderson. Oliver was the 2013 backup to Griffin Pickler and threw for 410 yards and two scores. Anderson threw for 95 yards. The other two quarterbacks are junior Dillon Gaither and senior Ryan Manley.Allman’s offense could really help running back DeMarco Corbin reach big numbers. Battling through injuries in 2013, Corbin only rushed for 371 yards.The defense will have some veterans in the secondary, led by free safety Ryan Phillippe and strong safety Jared Crouch. There is a nose guard in Jason Williams.
