After helping the US National Team to a 5th-place finish at the 1947 Ice Hockey World Championships, Ray was one of a slew of talented players who joined Colorado College after the second World War. He helped pushing the team to a 19-7 record in his freshman season and earning the Tigers a bid into the first NCAA Tournament. CC fell to Dartmouth in the semifinal but the team returned to the tournament the following year, only to lost both games by a rather large margin. Ray had one more chance to win a national championship in his junior season, and the team responded with one of the most overpowering offensive seasons in NCAA history. While the team again finished 2nd in the west behind Michigan, CC scored 167 goals in just 22 games, an average of more than 7.5 goals per game. Ray netted 26 of those markers himself and, in the semifinal against Boston College, Ray's 3-point night helped put the Eagles away. The Tigers made their first Championship appearance against Boston University and the two teams remained close after 40 minutes. In the third period, however, Colorado College exploded for 10 goals with Ray having a hand in half. CC won the game 13-4 setting a record for the most goals scored by one team in the championship game, the most goals scored by both teams in the championship game, the largest margin of victory, the most goals scored and the widest margin of victory in a Frozen Four. Ray's four goals in the Championship set a new NCAA record that has been tied twice but never surpassed as of 2020. His two assists also left him with 6 points which tied the NCAA record that still stands as of 2020. Ray holds the distinction of scoring the most goals in the final game of any player to not be named Most Outstanding Player. The 31 goals he scored on the year earned Ray a place on the AHCAAll-American Second Team while his tournament exploits went entirely unrecognized. Ray played one more year at CC before graduating and finished his college career as the Tigers' all-time scoring leader with 173 points in 99 games. Ray held the program record for 23 years until he was surpassed by Doug Palazzari during the 1973–74 season.
