This is not a full-on Lockbox, but rather a "pre-Lockbox." This has all the conference leaders (potential automatic bids) along with the at-large teams that seem (to me) nearly certain given their performance thus far. Now, it is still very early, but I would be utterly shocked if any of the 13 at-large teams I put in somehow miss the bracket in March.
The purpose of this pre-Lockbox is to give a sense of how many AL slots are actually out there. I have reasons for choosing these leaders and AL teams, but it's pretty easy to poke holes in my logic at this early stage. The picture will become clearer and clearer as we go along.
Remember, with the expansion to a 68 team bracket, there are now 37 slots for AL teams. So, if these 13 are pretty much certain, the rest of hoops nation is battling for about 24 invitations if they do not win their league's auto bid.
I will put together a full Lockbox soon and an initial bracket sometime before mid-January.
