Who wins, who's overrated and what's the best game? NBCSports.com has the answers for each region. For other regional analysis, click here: East | South | West.

Underrated
By nearly any measure, West Virginia is way too good to be a No. 6 seed. The Mountaineers (23-11 overall, 10-8 in the Big East), played the 8th toughest schedule in the nation, are ranked 8th on kenpom.com and 21st in RPI, ahead of teams like Illinois and Gonzaga. It's similar to last season, when West Virginia was a seven seed and was a bucket away from beating Xavier and earning an Elite Eight berth.

As if that's not enough, the Mountaineers are coming off a win vs. Pitt in the Big East tournament and a 74-68 overtime loss to Syracuse. Bob Huggins' team can play. Dayton and Kansas are about to find that out.

Overrated
Boston College is perplexing.

The Eagles have beaten North Carolina, Duke and Florida State, but have lost to Harvard (at home!), St. Louis and N.C. State. They feature one of the nation's elite scorers in Tyrese Rice and a highly efficient offense, yet have struggled since early February, losing five of nine.

B.C. now faces an incredibly athletic and highly efficient defense in USC, which has won five straight games. How do they handle DeMar DeRozan, who's averaging nearly 20 points a game in that span? Answer: They don't.

Most likely upset
Utah won 24 games, swept the Mountain West regular-season and tournament titles and ranked 9th in RPI. Their reward? Facing Arizona, which was probably the last team in the tournament. It's not a good thing, though. No. 12 Arizona is going to upend No. 5 Utah.

The Wildcats (19-13) lost five of their last six games, but are one of the field's most dangerous teams. They've beaten Gonzaga, Kansas, Washington and UCLA and only have one bad loss, a 76-70 setback at Stanford. With future NBA players like Jordan Hill, Chase Budinger and Nic Wise on the floor, Arizona can play with anyone. Hill alone will make life miserable for the Utes' 7-2 center Luke Nevill.

Best matchup
North Dakota State and Kansas will be entertaining (the Bison make 40 percent of their 3-pointers, which will keep the defending champs off guard), but a potential second-round matchup of Wake Forest vs. Arizona is the doozy.

There could be seven future NBA players on the floor at any given time, including five potential lottery picks, making for an impressive display of athleticism. Can Jeff Teague be contained? Who will check Al-Farouq Aminu in transition? And how many times will Jordan Hill dunk over Chas McFarland?

The over/under on jaw-dropping moves and ri-DUNK-ulous alley oops? 10.

Impact player
During the last four minutes of Ohio State's Big Ten tournament win against Wisconsin, Evan Turner took every shot. OK, nearly every shot. Why not? The Big Ten's best player is a 6-foot-7 swingman capable of running the show, making a defensive stop or carrying the offense.

The eighth-seeded Buckeyes will need him to be all-world to reach the Sweet 16, though. That means being even better than his usual 16.9 points, 6.9 rebounds and 3.9 assists an outing if they expect to get past top-seeded Louisville.

Regional champion
Louisville is the tournament's top overall seed, but it better be on its game. The Cardinals' path to the Final Four is loaded with potential pitfalls.

If they get past the Arizona-Wake Forest winner in the Sweet 16, they will face any one of these elite schools: No. 2 seed Michigan State, which rivals the Cards in athleticism and boasts more size; No. 3 seed Kansas, the defending champ loaded with a young, deep roster; or No. 6 West Virginia, which lost twice to Louisville by nine total points.

The Cards are ready, though. They swept the Big East regular-season and tournament titles for a reason.
