March Madness: The NCAA Tournament's four regional champions will be ...

We've covered a lot of ground with the NCAA Tournament this week.

In short order, we've offered various keys to building the perfect bracket, devised ways to get hired by billionaire Warren Buffett in three days' time, detailed the best odds for choosing the Sweet 16 and regaled the most iconic buzzer-beater finishes in the history of this grand tournament.

But, there's one last to-do job on the checklist: Providing an actual road map to winning your NCAA bracket pool ... which closes today at 12 noon EST.

One last note: The bolded matchups below are essentially 50/50 games, where readers are encouraged to go the other way, if they see fit ... since we had either team losing in the following round anyway.
