Typically such distinctions for front office overhead are meaningless, as all the profits run through the various teams comprising the league (who are not non-profit) the change means little for the front office, but the common rabble being mostly idiots hear the words "NFL", "BILLIONS IN REVENUE" and "TAX EXEMPT" and they think the rich are once again getting some huge break the average schmuck doesn't get, but not in this case. And since most stadiums (with the exception of the Cowboys) are funded by local municipalities there isn't a funding benefit that hasn't already been granted by eager politiwhores. This is an image-driven change only, I assure you, it won't impact the league in the slightest otherwise.
