Whose pockets do suppose will be lined by the profits from these events? The stadium is privately owned, and should be privately maintained. Miami-Dade has bigger fish to fry(public education and roads at the very minimum) than pay for stadium upgrades for a super bowl that will be in town once every 5-10 years.
Ross gets little to no gain for the ticket revenue.
The Super Bowl Committee uses the revenue to pay for special events during the Supr Bowl and for performers.
