Thats because I honestly feel if it fell over tomorrow it would be good for the city. Windsor is the worst possible place to put a replacement football stadium, for the politcal, security and tranport reasons I started off with. If it fell over tomorrow, NI were (presumably) playing their games at Ravenhill, and Linfield ceased to be subsidised by the international team, it would be good for football and the city as a whole.
And if you think Ulster would ever consider playing rugby at Windsor Park your dreaming. If you think the same about Ireland i woud suggest you speak to your doctor about some new medication. Croke Park was tricky enough.
I take your points about horse trading in the executive, but the other horse will be the "shrine to terrorism" at the maze. I don't know if Nelson McCausland or his colleagues will consider that a price worth paying. If a stadium is going to happen I think theres much more chance of it happening through Belfast City Council, especially once it gets bigger and has a bigger budget
