A 20-win season isn't very meaningful anymore. It's a poor standard. A 20-win season used to put you in a good position to earn a tournament birth--but not today. In the 1974-1975 season, BYU played 26 games. If you won 20 of 26 games you won 77% of your games. That's why a 20-win season meant something. Last year, BYU played 34 games (plus one NIT game). If we had won 20 games last year, we would have won 59% of our games (nothing to brag about). So a 20-win season isn't so remarkable. A 20-win season today is comparable to a 15-win season in the 1970s. Nobody considered a 15-win season in the 70s a great achievement. And we shouldn't consider a 20-win season a great achievement today.
