I know Sunbright has a low enrollment to begin with, which obviously means quality and experienced depth will always be an issue... especially with O and D linemen. I think they run a single-wing type offense, which is exactly what you want to do to keep the clock running and make games "shorter". However, you have to an OL than can at least get you 3 yards per play to do this. If they can get you 3 to 3 1/2 yards per play, you keep scores low and even give yourself a chance to win... especially if the defense can at least make the opponent earn their TDs and, again, keep that clock running.
From the looks of their scores, they struggled with both. I would imagine Sunbright's struggles begin with the very low enrollment.
A good strength and speed program + continuing to keep things simple and master their jobs can help as the kids mature. But, it takes time and follow through... and that makes it tough in today's age of "I want it now".
One plus at Sunbright is I believe it is a K-12 school. Get a "feeder" strength & speed program going in elementary and middle school and start developing those youngsters early on. Get your younger teams running the same schemes, yet modified for their age, as the varsity team is running. Lots of great benefits to working in a school where you can see and work with all the kids in the feeder levels each day.
Rooting for the Blue and Yellow Tigers.
Serious question: how in the world did they manage to beat Coalfield this season?
