In his 33 years as Tufts Head Coach from 1971 to 2004, he led the team to an overall record of 268-81, producing 92 Division III All-American swimmers, and 2 National champions.

[5] That year he came within 1 second of breaking a pool record swimming the Medley Relay,[6] and he would continue to win events in freestyle, butterfly and breaststroke as a young swimmer.

Swimming the breaststroke leg, he helped set an Irondequoit pool record for the Indians in January 1965 in the 200 Medley Relay with a combined team time of 1:50.6.

Bethany placed first in the President's Athletic Conference Swim Championship at Case Western Reserve in Cleveland during Megerle's Freshman year.

[10] Megerle swam at Bethany during the tenure of six-time All-American backstroker Wes Anderson who won All America honors in the Medley Relay on three occasions between 1967-68 as well as in the 100 and 200 back.

Conference administrators began to see athletic programs as "crucial extracurricular activities", that could complement rather than diminish the critical place of academics.

Pete Coassin was a 1980 four-time Division III All-America swimmer, who helped lead Tufts to a 36-5 dual meet record during his four years on the team from 1979-1982.

[14] Skilled at keeping his teams at Tufts happy while motivated and focused, in 1998 he wrote "To perform well at any level, the athlete must understand that stressful thoughts create muscular tension that eventually interferes with your freedom of motion".

Confirming Megerle's focus, in 1977 Division III All-American swimmer Dave Linstedt said,"You have to credit the coach for our success.

The Tufts Jumbos Men's Swim Team continually placed high in conference standings, and won the NESCAC conference in 2018, led by Engineering student swimmers Roger Gu and Michael Manfre, though Megerle had stepped down as Head Coach over a decade earlier.

Megerle's swimmers knew their Coach's light touch and sense of humor could reduce tension during tough meets.
