15 years ago when I coached basketball, jeans weren't considered disrespecting the game.
Actually, in most parts of the country it was and still is. Around here you'd be hard pressed to find a BB coach on the floor during a game that isn't in at least a button down shirt, dress slacks, and a formal dinner jacket. Most of them still wear ties with it...even at the MS level. I'm not judging anyone nor am I telling anyone what to wear. All I'm saying is what is generally known throughout the sports community and that proper attire for the sport shows respect for yourself, your team and the game.
