The Madness is underway.

In recent years, more and more people are choosing 16-1 upsets. Why so? After all, since the field reached at least 64 in 1985, the 16 seed is 0-128 against the No. 1 seed. It is the only seed without a win in the tournament.

Perhaps we’re just more aware that, one of these years, the number is going to come up for a No. 16 seed and, when it does, we’d like to say we called it. (Without admitting, of course, how many times we didn't call it.)

2016 Matchups Picked

The No. 15 seed has won eight of its 128 games vs. the No. 2 seed. That probably leads to a sprinkling of No. 16 picks, too.

Another possible reason No. 16s seem increasingly attractive: The number of people who pick brackets online is increasing. Though you'd think percentages would stay constant, if a growing audience means more casual fans, perhaps that means more who are willing to take a risk -- or less aware of how risky it is for your bracket.

Bracket experts will tell you that picking a No. 16 seed is a horrible risk-reward proposition. Since a 16 seed is unlikely to advance to the Sweet 16 as well, that huge upset pick is liable to earn only a single point in your bracket.

The moral: A No. 1 seed still is the most likely NCAA Champion and Final Four participant. So picking the upset might be good for bragging rights. But it could take you out of contention very early if you're wrong. And everyone who's ever picked a 16 seed has been.
