I would say at Montini over the past 6-7 years that 90-100% of the starting corners went on to play college ball as well as 85-100% of the starting two wide receivers went on to play college ball.
How about JCA and Geneseo?
As I stated in my previous post, a system like JC does not put their best athletes at the WR position and does not develop them. I cant give you an exact %, but JC routinely sends DB's to college. In addition, Montini has been more successful than JCA over the last 6-7, which means they probably have better personal, which means more kids playing at the next level. I dont think the offense Montini runs is the reason it is sending DB's to college. They are sending DB's to college because they have quality athletes.
