I understand about college. But their teams are generally 12-15 players deep. You can throw goons out there just to use up the foul count and protect your starters at the end of a close game.
In a C size school, (Michigan has A B C and D classes) like us, 20 district kids from being a class D, we have 4 on the bench. Meaning an injury and foul trouble means I have to suit up.
