While I'd love (and at the same time loathe) to see a new "MSG" (if that is what it's going to be called), you must consider the fact that the Dolans are really in it for the money. And the other thing to consider is the fact that they may not be able to retain the little "tax deal" that makes the current Garden so profitable, even if its obsolete and may cost alot in terms of upkeep. So a new "Garden" must be far more profitable than the current one.
Building this new arena where they want to build it will be an excercise in NY politics and public opinion.
It will happen... thats a fact. But when? That's the hot tamale.
