And, for the second year in a row, people across the country had to rip up their brackets, left with no chance of winning because they didn't see Morehead State bumping off Louisville, Butler making another run to the round of 16 or any of the other how'd-that-happen games.
Next up are the regionals and there are still plenty of great teams, players and story lines.
Here's a few things to keep an eye on while you're planted in that worn down recliner.
Jon Leuer and Jordan Taylor, Wisconsin. Leuer is a big banger, but also has a deft touch from the perimeter. Taylor is difficult to keep out of the lane, can also shoot outside and has a knack for making big plays.
Kyle Singler and Nolan Smith, Duke. Smith became the first player to lead the ACC in scoring and assists, while Singler is as multidimensional as they come.
Matt Howard and Shelvin Mack, Butler. Howard is a guy who could get his teeth knocked out and not slow down. Mack has quietly become one of the country's best guards.
They're all marquee at this point, right? Well, some have a little more pizzaz than others.
Ohio State vs. Kentucky, East Regional, Friday in Newark, N.J. There's going to be so many athletes on the floor it's going to look like an All-Star Game.
Arizona vs. Duke, West Regional, tonight in Anaheim, Calif. This one's worth watching just to see what Arizona's Derrick Williams will do next. Throw in the defending national champions and it's time to let the couch mold around you for 21/2 hours.
BYU vs. Florida, Southeast Regional, tonight in New Orleans. One word: Jimmer. Well, that and watching to see if CBS announcer Gus Johnson gets fired up when Fredette starts pouring 'em in.
2: Big East teams remaining out of a record 11 to get in (UConn and Marquette).
3: Number of ACC teams (Duke, North Carolina, Florida State) in the round of 16, most of any conference.
5: Times Ohio State and Kentucky have met in the NCAA Tournament, all won by the Buckeyes.
23: Years since Richmond reached the NCAA's round of 16.
191: Combined points between BYU and Florida in the first round last season.
