I think one year the Nets had to forfeit a playoff game at Commack because the floor was in such bad shape or it rained inside or something. Found this online.
Ironically, the team had forfeited its previous year's playoff game due to unplayable conditions at Commack. In 1969, Basketball Weekly reported that: "The court [at Commack] is placed over an ice rink and at times moisture seeps through the floor. Also, the areas behind the baskets are not fully covered and players driving in for layups often wind up on the ice. The Nets' Levern Tart suffered a broken cheekbone when he took a dive on the ice." Tart remembers seeing Denver Rockets players don gloves and overcoats while on the bench during a game.
