Dr. Jeremy Bettle, who has been the Nets nutritionist and strength & conditioning coach since 2011, has left the team to join the Toronto Maple Leafs as their Director of Sports Science & Performance, the Maple Leafs announced Monday.

Bettle was a mainstay in social media posts from players, and might be most notable for the above video, when he put Nets sideline reporter and standout basketball player at DePaul Sarah Kustok through the ringer in a typical player’s workout.

In a statement, Maple Leafs assistant general manager Kyle Dubas thanked Nets general manager Billy King for “affording us the opportunity to approach and hire Jeremy away from them.” From the release:

Prior to joining the Nets organization, he was a strength and conditioning coach for Team USA Men’s Basketball at the 2012 London Olympic Games. From 2009-2011, he served as the assistant director of sports performance at the University of California Santa Barbara, where he managed a team of sports performance coaches as well as over 450 Division I collegiate athletes from 11 different sports. Bettle holds a Ph.D in human performance from Middle Tennessee State University. He also has a M.S. in exercise science from Middle Tennessee State and earned a B.S. in sport and exercise science from Leeds Metropolitan University (England). He is a member of the National Strength and Conditioning Association (NSCA). Bettle, 34, is married to his wife, Michelle.

It’s not clear who the Nets will hire to replace Bettle, whether they bring someone in from outside or promote someone already in the team’s health department. Either way: we wish Jeremy well in his new position.
