Carroll used its bye week to heal some of its wounded and prepare for the District 4-5A season, which begins at 7:30 p.m. Friday at Dragon Stadium against Keller Central.Coach Hal Wasson said he gave his team Monday and Friday off and went through heavy workouts on Tuesday, Wednesday and Thursday.“What I like is that we went hard and accomplished a lot,” Wasson said. “You want to keep improving what you do, and I think we continue to grow. We have everything installed. It’s just a matter of maturity.”The maturity comes with junior quarterback Ryan Agnew. Wasson said he liked Agnew’s pocket presence in terms of looking for second and third reads. The more reps, the better off Agnew is going to be.Without question, this program has maintained a standard of excellence for the better part of four decades. So there isn’t a lot of required discussion pertaining to getting ready for district play and its significance.“I don’t have to say anything to them,” Wasson said. “We really don’t do anything different in this week as we are for the next week and the week after. They know what they have to do.”Injury updateThe Dragons are pretty much at full strength going into Friday.• Running back A.J. Ezzard (ankle) – should be at 100 percent, although he played against Temple.• Wide receiver Parker Fentriss (ankle) – should be 100 percent, also played against Temple.• Wide receiver Ryan Weigel (undisclosed) – don’t look for him to return anytime soon. But we’ve been reporting that for several weeks now.• Safety Tariq Gordon (undisclosed) – he also played against Temple and should be fine.Staying the courseWhile District 4-5A enjoyed its bye week, another area district (7-5A) began play last Friday. The notable game was DeSoto hammering Cedar Hill, 47-20. That district will play for two weeks before it moves into its bye on Oct. 4. In that sense, the district split its season in half – playing five games, getting the week off and then moving into district play.However, Wasson likes the way this schedule format has worked for his team.“I like the bye because you can review a lot of things before you start district play,” he said. “With district, I like the grind through the season for seven weeks. You want to get your team in a rhythm.”About Keller CentralThe Chargers (1-2) opened the season with a 24-7 loss to Flower Mound, defeated Saginaw Boswell 17-3 and lost a heartbreaker in the final moments to Arlington Lamar, 35-28.Bart Helsley’s team always finds a way to grind out games. This group isn’t flashy. Quarterback Jake McClurg is in his second year to start. This year, he’s thrown only one interception in his first 62 attempts. You could call him the consummate game manager. He also leads the team in rushing with 162 yards.The Chargers have done a pretty good job taking care of the football, committing only two turnovers. They are plus-3 in the turnover ratio.Central is going to have to find a way to create some turnovers and take some offensive chances if it’s going to hang with the Dragons. Carroll is 3-0 lifetime against the Chargers, including last year’s 59-0 blowout.
