How difficult perfection?

My oldest son has an 18-year old child. He (the son) was not yet one year old the last time there was an undefeated team in NCAA Division 1 basketball (Indiana in 1976). That is a staggering fact, given the fact that twelve teams had done it from 1938 to 1976. Even "Rent A Championship" Sleezipari has not been able to do it. Pretty remarkable.
