I think you have to break the GMC down into tiers this season, with anybody being able to beat anybody on a given tier:
Elite
Colerain - Does everybody forget how much talent this team has? Deshawn Pace is the best returning defensive player in the league, they're going to be good on both lines with plenty of talent and experience returning, and I'm sure they will find good athletes to run their triple option. They aren't losing in the league.
Good
Princeton - Very good collection of top end talent being gathered, but also have some really good lesser known players like RB Thomas Boyd. The big question mark is will their coaching staff (and offensive and defensive schemes, playcalling, game management, etc.) be any better than the dumpster fire that it was last year? They also aren't going to be that deep, so any injuries to their top guys will hurt more.
Sycamore - Only lost 8 seniors from last years 6-4 team and everybody knows how good this staff is. I'm not sure there is a single FBS player on this team, but they have very good talent across all of the starting positions and should be the Sycamore team -with the fewest holes in quite some time. No depth as always, but don't count out Sycamore's ability to out-execute their opponents on both sides of the ball.
Fairfield - Jutahn McClain is the best offensive player in the league, and Ellis should be a good QB. Krause is a very good coach and they actually have decent talent back on defense.
Mediocre
Mason - The defense was the strength of their team last year, and only 2 starters return. The offensive core is back, but it was atrocious last year and Mason runs a very poor offensive scheme. Should have more depth than most, but just not enough top end talent and coaching to compete with the tiers above.
Lakota West - Yes, they aren't there yet. They were a complete dumpster fire on offense last year, and we have no idea what kind of offense Bolden is even going to run yet. If its the triple, top end talent isn't a necessity, but West also doesn't have the years of practice that the Colerain kids do running it. They do return 7 starters from a solid defense.
Meh
Lakota East - Only return 6 starters from last year's playoff team. They are solidly coached, but don't exactly have tremendous talent in the pipeline. They won't beat themselves, but their also not going to wow anybody.
Hamilton - They actually have a tremendous amount of offensive talent, with potentially 4 power five players at their offensive skill positions. For the love of all that we enjoy in football, can somebody make this a dynamic offense?
Bleh
Oak Hills - Will never have success in the GMC trying to chuck it around. Also can't play defense. Ever.
Middletown - Presumably, they will be better than they were last year.
