Doctor, I always enjoy reading your insightful posts, but I have to respectfully disagree with this. The culture in a locker room is deeply enhanced and developed by the leadership at the top. It filters down and permeates throughout the team. If team's have strong leadership in the locker room, this culture exists and everyone is on the same page supporting each other ... if there is not strong leadership in the locker room, dissension exists and you have a fractured team. This strong team cohesion may result in more wins, however, there are other very important factors which determine wins/losses.
