I know the feeling. You’re nervous. You know the big names -- Ben McLemore, Victor Oladipo, Trey Burke -- but who’s this Nate kid I keep hearing about? Let me help you. Here are 10 mid-major stars who could really mess up your bracket in the coming days.

Mike Muscala (Bucknell) -- The Muscala Monster is a dangerous creature. The Bison are capable of upsetting Butler in the second round Thursday in Lexington because they’re led by one of America’s most underrated stars. He scored 25 points and grabbed 14 rebounds in a two-point loss to Missouri in January. Muscala (19.0 PPG, 11.2 RPG) dropped 18 points in a win against NCAA tourney participant La Salle in December. He’s finished with 25 points or more in 10 games. He also has the strength of 10 men. Not really, but he’s legit and more than prepared to help Bucknell ruin brackets worldwide.

Nate Wolters (South Dakota State) -- He plays with a chip on his shoulder. Few Division I schools sought his services when he was a high school standout in St. Cloud, Minn. Every season since, however, Wolters has proven he was clearly overlooked. He led the Jackrabbits to their second consecutive NCAA tournament appearance via a silky game that’s caught the attention of NBA scouts. He’s one of the nation’s most explosive offensive performers. Wolters (22.7 PPG, 39 percent from the 3-point line) recorded a Division I-high 53 points in a Feb. 7 win against IPFW. He’ll make Thursday’s matchup against Michigan in Auburn Hills interesting.

Will Cherry (Montana) -- Damian Lillard is arguably the top player in the NBA’s rookie class. When he was a Big Sky star at Weber State, Cherry was his top adversary. The senior is known for his defensive prowess (1.9 SPG), but he’s a talented offensive player, too. Cherry is averaging 13.9 PPG for a Montana team that will face Syracuse in San Jose on Friday. The Grizzlies don’t have top scorer Mathias Ward, who is out for the season with a foot injury. But Cherry is a proven leader. He’s tough, too. He missed a few games in early March after aggravating a foot injury that cost him the first few months of the season. But he hasn’t shown any signs of regression since his return.

Siyani Chambers (Harvard) -- The West Region is probably the easiest region. With Gonzaga as the 1-seed, it just seems more wide open than the other three. So expect the unexpected. Harvard could spur some madness in its second-round matchup against New Mexico in Salt Lake City on Thursday. The Lobos are the better team. But the Crimson have overcome adversity to reach this point. Stars Kyle Casey and Brandyn Curry left the team prior to the season because of an academic scandal. Chambers (12.9 PPG, 5.8 APG, 44 percent from the 3-point line), just a freshman, helped Tommy Amaker’s squad recover from those losses and earn another automatic berth with its second straight outright Ivy title.

Matthew Dellavedova (Saint Mary’s) -- The senior was a member of the Australian national team in the London Olympics. He’s struggled in his past two games, but Dellavedova will be ready for the NCAA tourney. The Gaels will face Middle Tennessee in Dayton in the First Four on Tuesday night. If they get past the Blue Raiders, they’ll see Memphis in the next round. Dellavedova (15.8 PPG, 6.4 APG, 38 percent from the 3-point line) is not just recognized as a mid-major star. He’s one of the best point guards in America, regardless of level. He’s talented and experienced. And he might help the Gaels nullify your bracket.

Jamal Olasewere (LIU Brooklyn) -- I don’t think we’ll see the first 16-over-1 upset. But if it is to happen, I pick the Blackbirds to pull off the feat. Why? Because Olasewere (18.9 PPG, 8.5 RPG) is a tough matchup for any team in the country. The 6-foot-7 forward is active inside, and he’s efficient in transition. The Blackbirds must get through James Madison in the First Four in Dayton on Wednesday. If they do, they’ll see Indiana on Friday in Dayton. If something crazy happens, Olasewere will certainly be involved.

Lamont “Momo” Jones (Iona) -- Iona is second in America with an average of 80.7 PPG. Jones, who started his career at Arizona, is the catalyst for the Gaels’ offense. He’s averaging 23.0 PPG, third in the nation. He’s recorded 30 points or more in six different games. He’s certainly a potent performer who guides a Gaels squad that can score in bunches. Iona, however, is facing one of the hottest teams in America right now. Ohio State has won eight games in a row, a streak that the Buckeyes capped with a Big Ten tournament title in Chicago on Sunday. But the Gaels play fast (17th in adjusted tempo per Ken Pomeroy). And their defense is porous. Still, Iona can overwhelm teams with its high-powered offense. That’s what makes its second-round matchup against Ohio State in Dayton on Friday so intriguing.

Ryan Broekhoff (Valparaiso) -- The 6-7 forward from Australia cracked ESPN's "SportsCenter" recently when his buzzer-beating 3-pointer knocked UW-Green Bay out of the Horizon League tournament. He’s one of the top mid-major players in the country. Broekhoff is averaging 15.9 PPG and 7.3 RPG for a Crusaders squad that will face Michigan State on Thursday in Auburn Hills. The atmosphere will favor the Spartans, but Valpo will be tough. The Crusaders are a versatile team with an offense that’s ranked 44th in adjusted offensive efficiency per Ken Pomeroy. And Broekhoff is the key to that success.

Doug McDermott (Creighton) -- The Bluejays might be the most dangerous 7-seed in the field. They certainly hit a few bumps during Missouri Valley Conference play. Overall, however, they’ve been one of the top mid-major programs in the country. They have wins against Wisconsin, Arizona State, Akron and Cal. They lead the nation with a 50.8 percent clip from the field. Their defense is suspect (78th in adjusted defensive efficiency per Ken Pomeroy). But McDermott, their leader, is a legit star. He’s averaging 23.1 PPG and 7.5 RPG. He could really go off in the Big Dance. First, he has to lead his team through a tough opening-round matchup against Cincinnati in Philly on Friday. Creighton is definitely a sleeper in the Midwest Region.

Ian Clark (Belmont) -- On paper, there’s a lot to like about Belmont. The Bruins are a strong squad that’s faced some of the best teams in the country in nonconference matchups. Belmont can beat Arizona in the second round Thursday in Salt Lake City. And a Sweet 16 run isn’t a crazy concept for this veteran squad. Clark (18.1 PPG, 46.3 percent from beyond the arc) is just one of the weapons that the Wildcats will have to neutralize when the two teams meet. He’s a stud who could really disrupt brackets throughout the country.
