re: The NHL's top draft prospect is unable to do a single pull-up at the NHL combine

This vs KD not being able to bench 185 is a pointless argument without context. It is unlikely either guy was just sitting resting waiting to get on the bar/bench as far as I know they move from workout to workout at a decent pace so you could easily be able to complete a pull up/press at full strength but after fatigue you might not be able to.
