Comment: "As you may know many if not all professional teams have a dress code for their players and coaches as appropriate
dress is important."

IMO, looks stupid and inappropriate for NBA (and some NFL- at least some did in the past-Tom Landry) coaches to wear coat and ties.  Always getting sweaty with the collared shirt running up and down the sidelines.  Even the post-game conferences....who cares if Lebron or Stephen wears warm-ups or a t-shirt vs. a long-sleeve shirt and tie?
