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 197980. He was the first freshman to lead the team in scoring since Mike Antonovich in 196970. 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.

Question: Question: How old was Mitchel when the event where he served with the Union began? Passage:John Mitchel, the most committed advocate of revolution, had been arrested early in 1848, then convicted on the purposefullycreated charge of Treason-felony. He was sentenced to transportation to Bermuda, where he joined other convicts labouring on the construction of the Royal Naval Dockyard on Ireland Island. He was subsequently sent to Van Diemen's Land (in present-day Tasmania, Australia) where he was soon to be joined by other leaders, such as William Smith O'Brien and Thomas Francis Meagher who had both been arrested after Ballingarry. John Blake Dillon escaped to France, as did three of the younger members, James Stephens, John O'Mahony and Michael Doheny. Meagher and John Mitchel (who had been transported there before for political activities) both managed to escape and emigrate to the United States in the early 1850s. They served on opposite sides of the American Civil War: Meagher serving with the Union, for which he recruited and commanded the Irish Brigade, and Mitchel allying himself with the South and living there, sending three sons to fight with the Confederacy.
