2008-09: Kyle Rau led Eden Prairie HS in scoring as a sophomore with 27 goals and 27 assists in 30 games. Eden Prairie finished 27-3 and defeated Moorhead, 3-0, in the Minnesota AA high school state championship game. NHL defenseman Nick Leddy was a senior on that team. Rau was selected for the USA U-18 team that participated in the Ivan Hlinka tournament and had one assist in three games.
2009-10: Rau scored 42 goals with 43 assists in 28 games (including sectional playoffs) as Eden Prairie won the Lake Conference title. Eden Prairie fell to Minnetonka in the Section 6AA finals to finish with a record of 22-5-1. Rau committed to playing college hockey at the University of Minnesota in 2011-12.
2010-11: Rau ended his high school career in dream fashion, diving to knock a loose puck towards the net for what became the game-winning goal in a triple-overtime, 3-2 Eden Prairie win in the longest state championships game in Minnesota history. Rau’s twin brother Curt, a defenseman, assisted on the goal. For the season, Kyle Rau scored 41 goals with 40 assists in 31 games and was named Minnesota’s Mr. Hockey. Prior to the high school season, Rau competed in the Upper Midwest Elite League and scored 16 goals with 7 assists in 22 games for Team Southwest. Rau also played for the USHL's Sioux Falls Stampede; scoring 4 goals with 6 assists and was +4 with 15 PMs in 11 games. In the Stampede's playoff run to the USHL's semifinals, he scored 7 goals with 5 assists and was +5 in ten games. Two of his goals and five points came on the Sioux Falls power play. Rau was ranked 177th among North American skaters by Central Scouting and was selected in the 3rd round (91st overall) by the Florida Panthers in the 2011 NHL Draft.
2011-12: Rau was the second-leading scorer for the University of Minnesota as a freshman. He scored 18 goals with 25 assists and was plus-23 with 29 penalty minutes. He scored 9 goals on the Gophers power play as Minnesota finished first in the WCHA during the regular season and reached the NCAA's Frozen Four. The Gophers lost to North Dakota in the WCHA tournament semifinals but returned the favor a week later, defeating the Fighting Sioux in the NCAA West Regional final.
2012-13: Kyle Rau was the second-leading scorer for Minnesota in his sophomore season. Skating alongside center Nick Bjugstad, another Panthers prospect, on the Gophers' top line, he scored 15 goals with 25 assists in 40 games and was +12 with 22 penalty minutes. Minnesota tied St. Cloud State for first in the WCHA but suffered back-to-back losses in the WCHA semifinals and NCAA West Regional semifinal to end the year.
Rau is an agile and quick skater with impressive hockey sense. His ability to anticipate plays allows him to consistently find the one place on the ice where the puck will go and where he can have the greatest opportunity to score. His defensive play is often underrated, and despite his smaller frame he plays a tough, physical game. He has quick hands around the net, and is a tireless worker.
Rau will return to Minnesota for his junior year, and will be the team’s main offensive threat. After this season, there is a good possibility he could take the next step into professional hockey. His hockey sense gives him an advantage over many other smaller prospects, and may allow him to work his way into a scoring line role in the NHL.
