NFL Coach wants to wear a Suit what's the problem?

if you remember seeing Tom Landry wearing his trademark Hat&Suit you knew that was His style&you couldn't imagine him without His trademark Hat. Mike Nolan the new coach of the San francisco 49ers was trying to pay His Father a Tribute. the NFL won't allow any Caoch to wear anything but NFL Licensed Gear. I feel you should have the freedom of choice&also who would think someone would put up a stink about a Man wearing a Suit on a Sunday?? different era&different time before the League got so Corperate.
