This is why it's ridiculous, laughable, and hysterical for people to make championship predictions prior to the tournament (and for some fans, prior to 4-5 seasons ahead).
Could you imagine??! People saying Cal should win 2-3 more titles?? Could you please inform me who is going to be the 1 seed in the West region in 2019?
What a bunch of buffoons. The FACT is, whether it is cliche or not it is a FACT, that you cannot predict what is going to happen in a single elimination scenario. It's what makes the tournament so fun, and the predictions so STUPID.
So, to answer the OP's question: nobody knows. If you do know "when", then why are you on a message board instead of placing future bets for the 2018 basketball season? It's not won on paper, its won on the court, in a game-by-game scenario!
