Bloomberg did new FUNDING deals for construction with the teams, but the terms of the LEASE the Mets have -- who gets revenues, what rent/taxes are paid, etc -- was virtually unchanged from what Giuliani drew up. The Mets have a 40-year lease, their stadium is on a subway line. They have the development rights to Willets Point, not someone else. If you want to haggle on details of differences, which mayor put what into the deal... go right ahead. The point is, the arena/stadium situation is night and day different between the Mets and Coyotes, and the prime difference is the role the Glendale government played with the Coyotes.
As for the Islanders, again, you're haggling over details I'm trying to remember from years ago that have been put behind NYT and Newsday pay-walls since. Charles, James, who cares. The point is that the Islanders signed a deal with SportsChannel, Cablevision bought SportsChannel, and thus the clause converted from SportsChannel to Cablevision... and the clause had to be bought out.
The details are here:
TV SPORTS; Rich Cable Deal Lessens Isles' Misery (Published 1999)
It's behind a paywall. I found a page that cribs some lines from the article:
"Cablevision recoiled at the possibility of paying the Islanders 18 1/2 percent of total FSNY-MSG revenues. In the talks, the team got an extension through the 2030-31 season, which features yearly payments rising from $14.8 million next season and $17.5 million in 2000-1 to $36 million in the final year, and the possibility of lousy performances causing a breach disappeared from the final contract."
