Alright, been doing a little research:
The Tennessee High School single game rushing record belongs to Taeton Wink (Stewart County) with 572 yards in 2016.
My model projects Ben Franklin (not the dork who invented electricity) to have between 585-620 yards.
I'm still working on my model for game results, but early returns show Cornersville projected to score between 38-51 points, while it has Chapel Hill projected between 3.5-7 points.
I haven't made my own predictions yet (that will come Friday before lunch), but this is what my model shows.
