Fans take that signature seriously. They don’t want their team goofing too wildly with the vestment they love, the robe which the gladiators representing them wear into battle against other armies of other city-states.
There’s a fine line, then, between properly updating, modernizing, making more chic that which has been recognized as a standard in the community for seasons past, and letting that uniform become stale.
Think of all those years in which that jersey evoked the kind of passionate emotion that causes 10-year-old boys as well as 85-year-old grandmas, and all subsets in-between, to stand and scream and applaud and cry and, most importantly, quite willingly offer up any number of Benjamins for seats to watch their team play.
