Excellence develops with good coaching. This is true with academic work in the classroom, but it is more familiar on the athletic field.
Michael Jordan may have been the greatest basketball player of all time, but he attributed his success in large part to Phil Jackson, his coach on the Chicago Bulls. And Phil Jackson has continued to demonstrate the value of good coaching in his subsequent work with the LA Lakers.

Games that score cooperation require coaching as much as games that score competition. However, the skills needed to win in win-win sports are not the same as the skills that produce success in win-lose sports.
One fundamental difference between playing a win-lose game and a win-win game is the type of communication between the players on different teams.

Notice the communication between teams on the basketball court or the baseball diamond. The primary conversation between teams is through body language such as the head-fake or other maneuvers to deceive the other team to think the opposite of the player’s real intentions. Oral communication is usually in the form of razing – heckling, teasing, taunting – anything to unnerve the other team and break their concentration and focus.
We hear candid and constructive communication among team members and between their coach and team members, but the other team seldom hears these words. When a team needs to strategize or solve a problem, they take a time out and huddle together only with their coach. They stay out of earshot of the other team.
Teams sit on separate benches. In a win-lose sport, it would be treason if a player from one team walked to the bench of the other team to discuss plans.
Information about weaknesses within the team is especially confidential. If a player were to reveal to the opposing team confidential information about a specific problem a teammate was having, the coach might consider this betrayal grounds for suspension.

The players learn these lessons early in their experience with win-lose sports. Players quickly learn that the other team is the enemy from whom strategies and plans must be kept secret.

However, these lessons in secrecy, deception, and razing are the opposite of the skills needed in win-win sports. The coach who wants to build a team that can work successfully with another team to overcome challenges together needs to teach a totally different communication style and method.

From the time the teams arrive at the ballpark, the coach wants them talking to each other and getting to know each other. They sit on the same bench. They plan together and coordinate their strategies.

Weaknesses and strengths of the teams are discussed openly so the coaches and players can work together to offset weaknesses and capitalize on strengths of the combined teams.

One key to effective coaching of win-win games is processing the experience that grows from the games.
