Click around more on the Yahoo! tournament site.
You'll find the Pick Distribution page.
There you can find out what percent of the Yahoo entrants picked what teams to advance in each round.
For example, I'm the only one in this 27-member pool group to pick Texas to win it all. But Texas is the 7th most popular pick to win it all, with 4.4% of the few million entrants. Only the four number one seeds, Georgetown and UCLA are ahead of four-seed Texas. Texas is a big state, UT-Austin is a huge school, but I'm pretty sure there's only one reason the Longhorns are getting so much love to win it all.

Here's another interesting one. UCLA is the fourth highest vote-getter to get into the Final Four, with 38.8% picking them to at least get the Final Four, that's ahead of one-seed Carolina and popular two-seed Georgetown.
