Entering HC in the fall of 1946, Laska was a guard on the 1947 NCAA Championship team which finished the season 27-3 (including a 23 game winning streak). In his sophomore season, the team went 26-4 and again made the "final four", where they lost to Kentucky but defeated Kansas State to finish third nationally.
During Laska's junior season, Holy Cross began a record home winning streak of 43 games. The 1949-50 team compiled a 27-4 record and returned to the NCAA Tournament, dropping a first round tilt to North Carolina State. He finished that season with 253 points for an 8.2 points-per-game average, including 12 games in double figures and scored 20 plus points on three occasions.
The teams upon which he competed compiled an overall record of 99-19.
From 1952-1967, Laska was the Head Basketball Coach at Assumption College, where his teams went 224-96. He was the first non-alumnus to be elected to the Assumption College Hall of Fame. He also served as Director of Athletics from 1956-1986 and in 1975, the gymnasium at Assumption was named in his honor.
