Listen carefully! I know that you watch all the very good spread teams in college, and you are certain that a vibrant spread offense is the answer, Here is a HS fact.....you can ALWAYS run the ball, but you cannot ALWAYS throw the ball. The 2016 Lebanon QB could not throw it in the ocean. Sam Harp is a very good coach that took a (currently) bad job; he would have opened up his offense if it was possiblle...it was not!
Case in point.......MJ has been a spread type team for about the last 3 years; they started the season still trying to fling it, and they lost (2) early games. Someone at MJ realized that your "vaunted" spread offense was not getting it done; so they went back to smash and dash and running the clock and winning football games.
So does Lebanon need a young energetic coach absolutely, and there are some good local ones nearby. Gentry is one of those young energetic coaches with a pretty good pedigree; he has worked with Maynord (excellent HS FB coach), but there are others nearby; if they have even applied. So, getting a good young one is a really good way to go IMHO.
Here is what I am trying to tell you, Colleges have at least triple the time each week to work on their offense AND they get to go and recruit the appropriate type player needed for their type offense...........they can run what ever they choose to do.
In HS, you gotta go with what is in the building. If you do not have a PASSER (* denotes accuracy) AND catchers (* denotes ability to run after the catch). So, to make a blanket statement of the need of a spread offense is quite simply HORSE-HOCKEY!
