Are you saying that Nixon requested the August NFL meeting? Because that isnt correct. He just said he wants the task force to get the issues with the funding and the court cases settled by August. Obviously it's not a coincidence, he wants it done before the owners meeting because it makes them look better.
He did not request the owners to meet in August, the meeting was set by them, and frankly probably without even thinking about asking any of the current home markets if its good for them. Correlation doesn't equal causation, these are two different things here.
Also the Carson thing is the same thing Inglewood did, it was a lot of mostly nothing then, and a lot of mostly nothing now. The only interesting thing about it was they showed some more details about the stadium, it was a watered down pitch to what they showed the NFL. Carson is doing the same thing. Its honestly nothing, and means nothing, again just as it meant nothing when Inglewood did it last month (or two months ago, I don't remember).
