This could be said of anyone, but the truth is probably that more people saw that if you wait 4 weeks, he'll have a different opinion of almost anyone. The latest about-face he's made is on the Cal-Stanford B1G status. Now, they're apparently in if they can wait six years and take a 1/4 share, and Stanford is working on ways to get out of the ACC. Just a few weeks ago, he claimed they were never coming because Fox would say no, they bring nothing, etc.
With UM, it was always ND and UM because they are AAU members, until he claimed the AAU didn't matter that much, or FSU is "close" to getting AAU status, or Clemson is in a growing part of the country, etc. so they don't need to be part of the AAU. Once he adopted the FSU -B1G inevitability argument, suddenly the B1G or SEC wouldn't take UM because it is in Florida and you don't need two FL schools (ignoring the SEC's inclusion of Texas and the B1G's admission of UCLA/USC). Now, he's on to his "flagship" theory where only the bigger state schools are getting into the P2, but Stanford to the B1G is an exception because they'll come cheap and have great Olympic sports (ignoring the facts he previously said only football matters and only Fox will decide, Fox doesn't like Stanford, and that Cal is truly the flagship university in California).
I agree that he does appear to get some information ahead of time, and that he does have more knowledge than most of us who didn't work for a university. But he's all about driving revenue for his X account and the best way to do that is to appease his FSU fans and their incessant need to believe they're better than everyone. IF they or Clemson stumble this year and nobody is watching their games, he'll adopt the next theory about who will join the super B1G.
