Kozloff was Penn's shining light at Hutchinson Pool from 1963-65, breaking pool and school records left and right. In his sophomore year, Kozloff earned the Edward Hopkinson, Jr. Award for most inspirational swimmer. As a junior, he again was awarded the Hopkinson Award and was named a captain for the upcoming season after earning his second varsity letter in the pool.
But it was his senior year, 1964-65, that Kozloff will be remembered for most. For it was that season that Penn swimming's radiant light got even brighter. The Quakers competed in 15 meets that season and Kozloff won the 50-yard freestyle event in 13 of those contests and took second place in the other two. He swam the 200 freestyle against Navy and set a Penn and Hutchinson Pool record, while placing first with a time of 1:49.6. Throughout the Ivy League schedule, Kozloff was undefeated in both the 50 and 100-yard freestyle races and he won the 100-yard freestyle in every meet he competed in. He earned a total of 134 individual points, a Penn-record for points in a season, and was awarded the Frank Smith Memorial Award for most points scored. Kozloff won the Captain's Trophy during his junior and senior seasons and was named Most Valuable Swimmer in 1965.
After the regular season was over, Kozloff competed at the Middle Atlantic AAU Championships where he finished first in the 100-yard freestyle and was invited to compete at the Eastern Championships. Kozloff also earned a spot to compete at the NCAA National Swimming Championships in
As a collegian at Penn, Kozloff held the Penn, Hutchinson Pool and Penn Pool records in the 50, 100 and 200 freestyle events and was a part of the record-holding freestyle and medley relay teams. His 50-yard free record of 21.7 was the fastest in the country at that time.
