treating sports customers like cattle/sheep has worked for owners for the last 30+ years, they (and the athletes) continue to increase the cost of attending - far above the average rate of inflation - and the customers keep on buying no matter how ricuclously expensive it becomes. btw - look up the old h. l. mencken quote...
as much as you would want families to be a more important part of sports franchise marketing, they are not who big time sports franchises see as their target customers these days. it may be short sided to subjugate this potential resource to secondary status but families don't have the disposable income for big time sports tix prices and sports franchises can't afford to be cutting tix prices to lure them in. that's why the baseball minor leagues have thrived.
it is dumb for the met(s)s to "act" like the yanks, doubt the the family wants their product to have the appearance of being second to the yanks even if it is the right way to go in marketing. fred-o's ego wouldn't allow that. the 60's persona evaporated after winning the series, after that they became another mlb franchise.
aside from the few stars that you mentioned, the 80's yanks were awash in overpriced/under achieving free agents and the steady stream of columbus shuttle wanna-be's. all that and the negative persona of stein-grabber set up a situation where it didn't take much for the mets to overtake them. winning w/the aura trumps charisma these days and the yanks have carefully crafted the image that the met(s)s can't match. since the family intends to hold on to the franchise for many years to come, the wilpon/katz persona of incompetence will continue to play 2nd fiddle regardless
of on-field success. they and their ways of doing biz aren't going to change.
the dodgers haven't been in ny for more than 50 years, that franchise's ny shine has rubbed off many years ago.
if a ny location is the magic wand for national interest, then explain the nets, islanders and devils?
it's the dodgers success in l.a. that continues to get them national interest and keep it. if they were an inept business and provided a sub standard product their brooklyn shine would not have helped them 10, 20, 30 years later.
few of those who went to see the mets in other cities were converted, the went to see 'em lose. the mets don't have the sustained history of success that have made the lakers, pats, packers, yanks, dodgers, celtics, cowboys, canadiens "national teams" and regardless of who's operating the franchise it will be second-tier.
your ideas might have worked in the pre-free agent/big media era, but not now, sorry...
