Input: Question: How many National Championships has the college hockey team that Thomas Vanek played for won? Passage 1:Harvard Crimson men's basketball program represents intercollegiate men's basketball at Harvard University. The team currently competes in the Ivy League in Division I of the National Collegiate Athletic Association (NCAA) and plays home games at the Lavietes Pavilion in Boston, Massachusetts. The team appeared in the NCAA Division I Men's Basketball Tournament in 2014, where Harvard upset 5-seed Cincinnati 61–57 before being eliminated in the round of 32 by 4-seed Michigan State by a score of 80–73. In 2015, Harvard tied with Yale for the Ivy title with an 11–3 league record. Despite having lost to Yale 62–52 at Lavietes Pavilion on March 6, 2015, just eight days later Harvard won a playoff between the two at the Palestra in Philadelphia to determine the Ivy League's NCAA automatic bid by a score of 53–51. Harvard thereby achieved its fourth straight NCAA Tournament appearance while preventing Yale from reaching the NCAA Tournament for the first time in 53 years. Harvard was eliminated from the 2015 NCAA Tournament by UNC by a score of 67–65 after leading with under one minute to play in the game. 
 Passage 2:After playing junior hockey for the Sioux Falls Stampede of the United States Hockey League (USHL), Vanek joined the University of Minnesota Golden Gophers, leading the team in goals (31), assists (31) and points (62) in the 2002–03 season. In part due to his prolific scoring touch, the Golden Gophers won the 2003 NCAA National Championship. Vanek was named MVP of the Frozen Four tournament, scoring the game-winning goals in both the semifinal against Michigan in overtime and in the final against New Hampshire. He was also named Minnesota's team MVP for 2003, becoming the first freshman to receive the honor. He scored the most points by a Golden Gopher freshman in 2003 since Aaron Broten who scored 72 total points in 1979–80. He was the first freshman to lead the team in scoring since Mike Antonovich in 1969–70. His 31 goals also led all NCAA freshmen in goal scoring, and was fourth in the entire country. He was also the 2003 WCHA Rookie of the Year, the third Golden Gopher to win the award.
 Passage 3:Bundrick first worked with Pete Townshend in 1977 when he performed on Rough Mix, Townshend's solo collaboration with Ronnie Lane, former bass player for Small Faces and Faces. He was invited to play on the Who's album Who Are You (1978), but broke his arm falling out of a taxi at the studio door and was unable to participate in recording sessions. Bundrick toured with The Who from 1979 to 1981 along with drummer Kenney Jones and played on their album Face Dances (1981), then briefly parted with the band during the recording of It's Hard (1982) and the subsequent tour. Bundrick later rejoined the band performing with them at Live Aid in 1985 and played live with them until 2012.
