Numbers: 29-6-5, 1.55 goals-against average, .933 save percentage
Worth watching: Hartzell is the real deal and a strong reason that a team that's not loaded with stars has reached the Frozen Four. He's a Hobey Baker finalist, a senior and has largely been consistent all season.
Numbers: 11 goals, 11 assists
Worth watching: Root grew up in Mt. Lebanon and went to prep school in Connecticut where he was recruited by Yale. Root scored two incredibly timely goals last weekend to lead the Bulldogs past two perennial powers and their first Frozen Four since 1952.
UMass Lowell (Goalie)
Numbers: 20-2, 1.31 GAA, .953 save percentage
Worth watching: At 6 feet 4, 200 pounds, he is a massive presence in net and helped his team storm through the loaded Hockey East playoffs and the first two rounds of the NCAA tournament. A Winnipeg Jets prospect, he will be in an NHL goal one day.
UMass Lowell (Forward)
Numbers: 16 goals, 21 assists
Worth watching: Wilson is a Penguins draft pick, which earns him interest locally. But he's also the River Hawks' leading scorer with 16 goals, and 21 assists as a sophomore.
St. Cloud State (Forward)
Numbers: 13 goals, 37 assists
Worth watching: The second of two Hobey Baker finalists to reach the Frozen Four, LeBlanc is skilled and prolific and returned this year after a gruesome leg break in the fall of 2011.
Numbers: 15 goals, 15 assists
Worth watching: Peca scored a natural hat trick in a span of 3:12 in his team's rout of Union in the East regional. He is part of the team's top line with brothers Connor and Kellen Jones who all seem to be hitting their stride heading into the Frozen Four.frozenfour
