Physically - JJ’s catch is a much better feat. It was OBJ one hand + wrestling it from defenders hands + securing the ball with one hand while falling to the ground.
But still it’s close call, OBJ was the first one to do it, and like Roger Bannister’s 4 minute mile, it’s much more impressive than those that came after him.
Na, the defender caught the ball, and Jefferson wrestled it away from him with one hand. It wasn't a one handed catch like OBJ's.
If the defender wasn't there, I'm not sure if Jefferson catches it.
