Jason was a co-captain Senior year along with future HOF'er Nelson Santiago. He was elected to this position after 3 years of playing the hardest brand of rugby that Babson has ever seen. His nicknames of "Hulk" and "Moose" only begin to touch upon the style of play that Jason brought to the center position. Tackles were never missed, as a matter of fact they were their own art form. Opposition tackles were broken and shrugged off until multiple men were finally able to bring him down. Jason was mentioned in over 90% of team articles as either a try-scorer or man of the match.

His rugby career after leaving Babson has been equally as impressive. He was the first non-Irish captain of the Boston Irish Wolfhounds and has his jersey retired by Division 1 New Haven Rugby club after he left that team for work reasons.

Marcos ‘Circus Maximus’ Flegmann, as he was called in his later years for his imposing physical size and punishing play, left a lasting impact at Babson where he played for all four years and lead the undefeated 2011-2012 Fall team. Marcos was a leader on and off the pitch and a happy warrior at that. His talent was immense and he did things with such ease that it seemed almost effortless. He was Vice President of the team in his junior year and Forwards Captain his senior year.

After Babson, Marcos played for the Boston RFC in the American Rugby Premiership and recorded 14 official caps for the Mexico Serpientes, Mexico’s National Rugby Union Team. He also played with Argentina during the Maccabiah Games, and played with Mystic River Rugby Club, the USA Premier League 2016 National Champions.

Marcos lost his battle to cancer on December 21, 2020 and he is remembered with an annual Back to Babson Hospitality Tent at the pitch in his honor each year since 2025.
