Exactly. I mean, if he's trying to hide this big announcement until the magical day (apparently Tuesday), then why would he retweet that? If that information was out, which I don't think it is, you would just ignore a tweet like that. I don't think anyone outside the family or AAU coach knows what his decision is. I think a lot of people have assumed OSU because that was his last visit, the timing of the Goodluck announcement, and his twitter activity.
Or it's possible he doesn't care about hiding his decision and the hints he's been dropping are real.
