Pretty sure he was into athletics at that age. Specifically wrestling. So, this locker story seems more dubious than most made up stories.
Ah yes, wrestling, the sport known for it’s small, skinny athletes

I mean… kind of, but not really.

Dudes will bulk up and slim down to be as optimal as they can for their weight class, much like in other combat sports / martial arts.

It basically just depends on what weight class you’re aiming for, and while I can’t quickly find his specific weight or class:

Yeah that’s Neil, the captain of Harvard’s wrestling team.

Career record of 141 wins, 6 losses, 2 ties.

I’d wager from the photo he was between 180lbs and 210lbs at that time.

Neil is kind of like Dolph Lundgren in that he’s got a PHD as well as a substantial track record in a martial combat sport.

The entire premise of this image is quite ridiculous.

Some people are both quite intelligent and quite physically capable.

I was joking at the point that a 6’1" 180lb+ guy, much like the OP implies, would not be able to be physically shoved into a locker.

Ah, ok, my misunderstanding, we are in agreement then!

Either way, the info presented reinforces the unlikelyhood of an undefeated high school wrestling captain being bullied and shoved into a locker.
