In their defense, I think they're right to abandon Pier 40 as a viable stadium site for simple fact that there are too many rich people nearby who will throw everything they can in to stop this - hell,
look what's happened with the Pier 55 park proposal. But you're definitely right in that that's the model they need to look at. They need to be willing to put larger sums of money on the table and say, for example "We're going to give $5,000,000 to the Flushing Meadows Conservancy, $5 to an HPD housing stabilization fund, yadda yadda" That's the only way it's going to get done.
