Your typical coach is a control freak. They want to control every facet of every game, gameday and practice, and even how they conduct themselves outside of the rink on a daily basis. When MJ said "who wants it?" he is giving up control of the most important play of the game. I've watched coaches huddle on the bench and make a shootout list, adding numbers, scratching numbers off the list. They'd never in a million years give that control up. Sure, MJ could hardly go wrong with any of maybe 8 choices, but to throw that out there was just another example of his brilliance as a coach.
I watched the celebration today, sadly I could not make it yesterday. O'B was very pleased to exact revenge on TWSNBN. I love it.
