text: Money;  The NFL is obsessed with it and years ago they made all team apparel to be licensed under the NFL and if it isn't licensed, it can't be worn. \n\nCoach Nolan of the 49ers is the son of Dick Nolan, the former 49ers coach and Dick Nolan always wore a suit.  Nolan wanted to wear a suit in honor of his father and the NFL said no.  They then finally compromised and if it was made and licensed by the NFL then he could do it.  the No fun League strikes again.
