Duck!
Seriously, welcome to the boards. :welcome: There have been quite a few spirited discussions regarding this issue, with the consensus being that the team logo is fine as it is (history, tradition, etc.).
But Wayne Huizenga has another reason to keep a distinction between the stadium logo and his team logo -- $$$$. Not tying the stadium brand exclusively to the NFL team makes it more marketable for organizers of non-football events.
So, I wouldn't expect a change in the status quo anytime soon.
