Never thought this would happen quickly. Billion dollar deal.
Also, some of the most pertinent details are still TBD. How much land is available and where is it?
It seems like the smaller plot available from the NCC only large enough to build an arena is the only certainty other than maybe the current CTC site. Who would the winning bidder be dealing with for the land - NCC or the City? It depends on the site in question and of interest to the bidder.
If bids contained real estate focused partners, that would make it a much harder process. I think that's might have happened with the Remington bid. Reynolds was primarily interested in the team, while his other partners (Remington) were interested in the real estate. GSP, Melnyk's and the NHL don't own the land, yet they are leading or involved in the sale process. They can't make commitments on behalf of the NCC or City for the land.
It doesn't seem surprising that it's taking this long given these circumstances. Anyhow these are just a few thoughts (or speculation if that's the preferred word).
