Even at a school with a storied history of swimming success, the 1972-73 boys team was a standout. The only undefeated swimming team in school history, the boys finished the year with a 12-0 record. It is no surprise the team was comprised of six All-Americans: Jan Kaplowitz in three events: 50 Free, 200 Medley Relay, 400 Medley Relay; Tim Wallace in three events: 200 Medley Relay, 100 Fly, 400 Medley Relay; Tom MacDonnell in two events: 200 Medley Relay and 400 Medley Relay; Chris Stack in two events: 200 Free and 400 Free; Jay Cilfone: 200 Medley Relay; and Scott Nicholson: 400 Medley Relay.
In an average meet, the team outscored their opponents by 24.3 points, and the schedule included teams from the Coast Guard, Harvard, West Point, Williams, and Yale. Coach David “Duff” Tyler ’65 took down the Bulldogs—after years of coach Warner Babcock’s refusal to allow his teams to beat Yale, out of allegiance to the Yale coach, who was a friend.
