Last night I had my first game (NAIA) and both my partners were D1 officials. We walk out onto the court and guess what? A player was wearing socks that came above his knee! It looked like tights until he ran. We talked about it and there is no current rule against it. After the game, a ref doing the game after us (another D1 official) came in and asked about it. We told him they were socks and there currently isn't anything in the rule book that says they are illegal.
Other than that is was a good game. It was great to only drive 1 hour, have an early game and be home by 9pm.
