| UNDEFEATED TEAMS | ||||||||
| From 1933 through 1977, with few other post season tournament options, NYSPHSAA teams only had to win their own Sectional Tournament to | ||||||||
| finish the season unbeaten. In 1978 and 1979, when the State anf Federation Tournaments were reinstated and created respectively, Sectional | ||||||||
| winners played each other making it much more difficult to finish undefeated. Below is a list of teams I've found that have accomplished this great | ||||||||
| feat. If you have any additions or corrections, please contact me at rich@newyorkstatehighschoolbasketball.com. | ||||||||
| ** State & Federation Champion | ||||||||
| * State Champion | ||||||||
| # Excludes controversial season ending and often disregarded forfeit loss | ||||||||
| NOTE: Due to the Covid pandemic, we are only including teams for 2021 that have won 12 or more games. | ||||||||
