The NCAA Tournament's four No. 1 seeds are all still alive heading into the Sweet 16, which begins with regional semifinals Thursday, March 22. Two No. 2 seeds weren't so fortunate.

While No. 1s Syracuse (East), Michigan State (West), North Carolina (Midwest), and Kentucky (South) avoided upsets, Duke, No. 2 in the South, and Missouri, No. 2 in the West, were each knocked out by No. 15 seeds within hours of each other last week in the biggest shockers of the tournament. Lehigh upset Duke and Norfolk State took out Missouri, marking the first time a 15 had beaten a 2 since 2001.

College basketball's conference tournaments this week serve as the appetizer for the main course of March Madness that begins this Sunday when the field of 68 teams for the NCAA Tournament is revealed.

With conference realignment continuing to shake up the college sports landscape, the tournaments also serve as a farewell to some schools that will be leaving their traditional homes (i.e. Syracuse from the Big East to the ACC, Missouri from the Big 12 to the SEC).

PRESS RELEASE: "Veritix® Relationship with NCAA® Yields Another Successful
Ticketing Experience for the 2011 NCAA Men's Final Four®"

Houston, TX (Veritix) April 8, 2011 – Veritix®, the Cleveland-based state-of-the-art digital ticketing, event marketing and relationship management technology company celebrates another successful ticketing experience for the NCAA Men's Final Four.

A combination of a local school's once-in-a-lifetime appearance in the Sweet 16, as well as the presence of three successful schools with famously rabid traveling fan bases, and the lure of a delicious Elite Eight matchup has turned a ticket to the West Regional into the hottest ticket of the NCAA Division I men's basketball tournament.

According to StubHub.com, the average listed price on the resale market (through Wednesday, March 23) for a ticket to the West Regional semifinals tonight, March 24, at the Honda Center in Anaheim, CA was a robust $743.

A class action lawsuit against Ticketmaster and the National Collegiate Athletic Association (NCAA) concerning lotteries the two have conducted for years for Final Four tickets is continuing to wind its way through court, and justices are seeking an Indiana Supreme Court ruling as it moves forward.

This month, the Seventh Circuit Court of Appeals sent three questions to the state's Supreme Court for which they need rulings in order to adjudicate the case. At issue is whether the lotteries Ticketmaster and the NCAA run are considered illegal under Indiana law.
