With our 2024 event calendar on the horizon, our staff has dedicated some time to reflect on the top statistical performers that we saw at our events in 2023. We'll be shining some light on Illinois natives who put up loud numbers in 2023, showcasing their tools to our staff at PBR Illinois events.

These leaderboards were compiled solely based on numbers at our state events, including Preseason IDs, All-States, Open events, Scout Days, Future Games, and the inaugural All-American Game, too.
