losses from the 1950's and 1960's, since the Cougars weren't really in the tournament anymore.
The NCAA Tournament has taken many different forms. In 1972 #9 BYU had to play #5 Long Beach State in their first game. By todays standard that would be unthinkable. But back then, they tried very hard to keep regional opponents in tact, which resulted in a some horrid draws for BYU.
Trying to parse certain wins and losses as valid tourney games is stupid.
