The first Big 12 meetings in Phoenix have now wrapped up, and more information is starting to trickle about concerning which way the administrators are leaning. It certainly seems as if expansion is closer to happening than ever before, but if the most recent report from Chuck Carlton of the DMN is accurate, there's still plenty of room for some big surprises in this process.
