I don't doubt that the Weis teams had emotion and passion. I'm sure they did. But this video, to me, shows someone who knows how to lead people. It shows somebody who knows how to bring out the best in others and how to make it work for real world results. Just that thought, "to win you have to stop losing" is simple but brilliant.
In tennis there really is not much difference in skill between the number one player in the world and the number 100 ranked player in the world. The real difference is mental. It's how the number one guy prepares himself to win. It's how he thinks about the game as it's unfolding. This is what the coach is talking about, in my opinion. That's the stuff the separates the wheat from the chaff. We've all seen it in action. The guy who is in the finals for the first time, is kicking butt for a set and then something happens. The champ, who is losing, hits a great shot or just hangs in and the challenger starts to doubt. Mentally it starts to unfold for him and he's history.
