If you've followed this year's NCAA basketball tournament and you think there have been some real surprises, you're right. Of the five million brackets entered in ESPN.com's competition, only two (that's TWO), have predicted the 2011 Final Four correctly.

Some may have picked traditional powers like Kentucky and Connecticut, a few may have gambled on Butler, but suffice to say only two - for reasons known only to them - selected Virginia Commonwealth. The Rams, who only made the field of 64 after winning a "play-in" game, are the biggest shock inclusion among the basketball elite.

This weekend's event is live on ESPN and ESPN HD here in Australia and, if form holds, the final three games should be superb. Here's a rundown on the remaining teams:

Kentucky

Nickname: Wildcats

Location: Lexington, Kentucky

Undergraduate enrollment: 20,000

Coach: John Calipari, age 52

Final Four appearance: 14th (7 titles)

Best player: G Brandon Knight

Famous NBA star: John Wall, Washington Wizards

Notable alum: Actress Ashley Judd

In a nutshell: This is the third school that coach John Calipari has taken to the Final Four. The previous two - Massachusetts and Memphis - had their achievements erased after various NCAA violations, so it remains to be seen what will happen to UK after this year. Still, he's a remarkable coach and has perhaps his most well-balanced team in years.

Connecticut

Nickname: Huskies

Location: Storrs, Connecticut

Undergraduate enrollment: 20,800

Coach: Jim Calhoun, age 68

Final Four appearance: 4th (2 titles)

Best player: G Kemba Walker

Famous NBA star: Ray Allen, Boston Celtics

Notable alum: Actress Meg Ryan

In a nutshell: Consistently one of the country's best programs, UConn struggled early. Coach Jim Calhoun is a wily old-timer who knows how to prepare a team for a stretch run. He's got one big-time superstar in Walker, who has been tremendous, and a bunch of good role players.

Virginia Commonwealth

Nickname: Rams

Location: Richmond, Virginia

Undergraduate enrollment: 23,400

Coach: Shaka Smart, age 33

Final Four appearance: 1st

Best player: F Jamie Skeen

Famous NBA star: Eric Maynor, Oklahoma City Thunder

Notable alum: Author Tom Robbins (Even Cowgirls Get The Blues)

In a nutshell: This is an unbelievable story, with many experts - most notably ESPN's Jay Bilas - believing the Rams did not even belong in the tournament. Young coach Shaka Smart is the post-season's hottest property and with aggressive defense and timely three-point shooting, VCU has eliminated Georgetown, Purdue, Florida State and #1 seed Kansas.

Butler

Nickname: Bulldogs

Location: Indianapolis, Indiana

Undergraduate enrollment: 4,000

Coach: Brad Stevens, age 34

Final Four appearance: 2nd

Best player: G Shelvin Mack

Not-so-famous NBA star: Ralph "Buckshot" O'Brien from the 1950s

Notable alum: Notorious cult leader Jim Jones

In a nutshell: Last year, Butler was the Cinderella story. Now they're back in the Final Four for the second consecutive year and coach Brad Stevens has established the program as one of the country's best. The Bulldogs are a disciplined bunch who aren't afraid of the big stage and don't panic in crunch time.
