The league believes they can, particularly Rooney.
However it all comes back to what's best for the league and all the owners, not Stan himself - which is why its a "win/win" for Oakland and San Diego. They don't have any realistic options at this point, and are also the only two cities that don't have a realistic stadium alternative like St.Louis if they're told no. A big reason why I think Carson is the bigger money maker is: 1) two teams, 2)you're losing a market and not replacing it, while also competing with a near by market 3) Davis/Spanos don't have another alternative, and I don't think the other owners are going to tell Spanos to keep waiting for a realistic deal to come around, particularly after 14 years. People slam him for "dissing" San Diego's plan, but I've yet to see one that's viable or realistic.
If the NFL has proven one thing through this process it's that they're not going to wait for a city to get all their ducks lined up come decision time. Financing, land - everything has to be secured for when they say go, the construction starts immediately....Anything that has a contingency that the other owners/stadium committee feel could halt or kill the plan will not pass, let alone be determined viable. Just like if the Riverfront financing doesn't come through, the deal is dead unless Peacock has another magical way to secure the financing. I think that's actually a good example. The common belief is that the financing and land will all be wrapped up come August - do you think the NFL would hitch their wagons to that plan without a "Definite yes"? Nope, and we all know St.Louis has the strongest plan of the 3 cities.
