Besides recruiting, the easiest things to do better in my eyes is:
Shake up the coaching staff - get fresh blood in and change up what they're doing. For God's sake, run some plays under center for a different look once in awhile. Demonstrate some imagination more frequently and quit relying on always executing perfectly in the base offense/defense.
Get the damn ball to Papi White 15+ times a game every single game instead of the 4.9 times a game he is averaging right now. Move him around. Get him in space. Besides Nathan Rourke, he's head and shoulders the most dynamic player wearing green & white on the field.
When the other team stacks the box in a series and Ohio is -5 in yardage its time to throw downfield rather than waste three possessions UTM. Statistically if we throw deep to Papi enough times he'll make a play. Do the coaches not collect stats on play calling to find their statistical efficiencies?
