I only think it's odd that they decommited from UM, but then scheduled an official to SU (and only SU) 24 hours later. If they wanted to take more time to explore all their options, then why not decommit, take a couple weeks to finalize the last two unofficials, and then take some time to make a decision. This seems like test driving a Car A 10 times, and then buying Car B you test drove once, then taking it back to the dealer ship after a month, immediately taking another test drive on Car A, and then walking off the lot saying you still don't know.
I know, I know. 17 year olds.
