Part of it is the mercenary feel of the team, but the stadium is also a PITA to access, Little Havana isn't a draw in and of itself, and the ticket prices are high. Here's a good overview: https://www.fishstripes.com/2017/4/17/15310100/why-the-marlins-cant-fill-seatsI think in this case Jeter did a pretty decent job of pointing out that a rebuild in today's atmosphere doesn't necessarily have to translate into trading off all you best players for prospects and forfeiting any desire to win games on the field. So no, I personally don't think Ozuna goes too.
People keep stressing the surface "franchise player" factor, but this isn't TB having locked up Longoria early or a "we'll just look past the money latter if/when things go south" surrounding scenario we are talking about here. Miami is a team that flirts with sub-$100m payrolls, and even with Stanton blowing it up this season has seen their attendance drop for a 3rd straight year (27th).
In a perfect world sure, they keep and build a huge dice roll future around one guy making roughly 1/3 of their payroll. If their ultimate goal is to stay content at where they are now as a franchise it's probably the safer short term bet as well. I just doubt that's the new ownership's overall mindset going in though. Finding a more practical way to hopefully string together a couple of seasons that result in legitimate WC hopes/appearances can/will do more for that city/franchise then fighting a more uphill and losing battle with the Stanton show in tact ever could imo.
My money would be on Stanton getting traded this winter, and not for straight prospects.
Having a core of identifiable young players would help, but at this point I don't think trading Stanton would be that much of a hit to the fanbase. When I see him later tonight, I'll ask.
