Settle down. It's September. This is why message boards exist. No one is forcing you to click on this thread. If you think he's gone already than nothing in this ALL THINGS ALEX thread should interest you. When he commits, you'll find out.
One scenario: AAU coaches, parents, friends and others have been chirping in his ears for years to "take this decision seriously and do your homework" so he takes trips and looks around. Maybe he actually does want to be a Gopher but has a few doubts, or wants other information to make his decision, or waited too long. Not everyone is foaming maroon and gold at the mouth like us.
If everyone wanted "to be a Gopher that bad" on day one, we would fill up our scholly's an hour after they were offered. The idea that he may have anxiety about the most important decision of his life, or not be 100% confident, or just wanted to take his time is a real possibility. Did it bite him in the arse? Maybe, or maybe not.
This is in no way, shape, or form a prediction that he'll be a Gopher. It's just a perspective that you might not be considering.
