The only thing I know to be true about what will happen in the games of this 2019 NCAA Tournament, like any of the many before it, is that something unexpected will happen.
It’s never all chalk. It’s never all titanic clashes or historic upsets. That team you thought was a lock might shoot 30 percent from the field; the team you swore had no chance might get hot for an entire weekend. Last year brought us a No. 13 seed in the Final Four and a No. 16 seed in the second round, and it doesn’t even feel that crazy in retrospect.
