If L.A. Gets A Team, Seahawks May Move To AFC West

That day is coming, probably sooner rather than later. The lease goes through 2025. Will the Superdome still be good enough for the NFL in 2025? How much money will we put into it. The Superdome to me is going to be one of those timeless classic stadiums.. There have been others, wrigley field, solder field, yankee stadium, fenway, etc. but even Yankee stadium was eventually replaced. I'm in no hurry to move on from the superdome but one day it will happen.

I would not be surprised if the Saints get a new stadium after the lease. Like you said, even Yankee Stadium got demolished. The only problem will be to find a location as great as where the Dome is.
I know, when the lease ends, there will be at least, major renovations to the Dome if it stays.
