You’ve seen them on the sidelines of a Super Bowl or pacing the floor of a boardroom. Sometimes they’re quiet, scribbling notes on a laminated sheet. Other times they’re screaming until their veins pop. But if you actually stop to ask the average person what does the coach do, you’ll get a shrug and something vague about "motivation" or "calling plays."
It’s way deeper than that.
Honestly, a real coach is a mix of a mechanical engineer, a high-stakes therapist, and a cold-blooded strategist. They don't just stand there. They are the invisible hand that shapes how a human being—or a whole team of them—functions under extreme pressure. Whether we are talking about Bill Belichick in his prime or a high-level executive coach like Marshall Goldsmith, the core DNA of the job is the same. It is about closing the gap between what someone is currently doing and what they are actually capable of.

The Architect of the Invisible
People think coaching is about the "big talk" in the locker room. It isn't. In fact, most of those cinematic speeches are kind of a myth. What the coach actually does happens in the boring, quiet hours when nobody is watching.
They look for patterns.
A coach spends roughly 80% of their time observing things that the performer can’t see themselves. When you are in the middle of a game or a high-pressure sales pitch, your "self-talk" and your ego get in the way. You have blind spots. The coach stands outside of your head and watches your feet, your tone of voice, or how you react when you lose a point. They are basically a human mirror.
Take the "Inner Game" methodology developed by Timothy Gallwey. He changed the entire industry by proving that a coach’s primary job is to reduce "interference." If you’re a tennis player, you already know how to hit the ball. The coach’s job isn't necessarily to teach you a new swing; it's to stop your brain from overthinking the swing you already have. They remove the mental junk.
Why Technical Skill Isn't Enough
You’ll often see former star players fail miserably when they try to coach. Why? Because they can't explain the "how." They just did it instinctively. A great coach doesn't need to be the best player in the room; they need to be the best communicator.
The Feedback Loop
If you want to know what does the coach do in a tactical sense, it’s managing the feedback loop.
- They capture data (stats, video, body language).
- They filter out the noise.
- They deliver the "nugget" of truth that the person can actually use.
If a coach gives you twenty things to fix, you’ll fix zero. If they give you one, you might actually change. That selection process—knowing which 19 things to ignore—is where the genius lies. It’s about surgical precision, not a shotgun blast of advice.
The Psychological Weight
Let’s talk about the heavy stuff. Professional coaching, especially in business or elite sports, is basically applied psychology. You have to manage egos. You have to know who needs a kick in the pants and who needs a hand on their shoulder.
There's this concept in psychology called the "Pygmalion Effect." Essentially, if a coach believes a player is going to be great, they treat them differently, and the player eventually performs better. It’s a self-fulfilling prophecy. A coach creates the environment where success feels inevitable rather than lucky.
They also handle the "identity crisis" that happens after a loss. When a CEO loses a major deal or a quarterback throws a pick-six, they feel like failures. The coach is the one who disconnects the person’s value from the result. They keep the ship steady. Without that, the "yips" set in, and once you have the yips, it’s over.

The Strategy of the Long Game
In sports, we see the "X’s and O’s." We see the playbooks. But in the business world, the strategy is about resource allocation. A business coach looks at a founder and asks, "Why are you spending four hours a day on emails when you should be raising venture capital?"
They force you to confront the uncomfortable reality of your own calendar.
Different Flavors of Coaching
It’s not all the same. A "Directive Coach" tells you exactly what to do. Think of a drill sergeant or a technical skills coach. Then you have the "Non-Directive Coach," which is more common in the corporate world. They don't give answers. They ask questions that make you feel like your brain is melting until you find the answer yourself.
- Skills Coaching: Fixing the literal mechanics of the task.
- Performance Coaching: Getting the most out of existing skills during a "live" event.
- Developmental Coaching: Looking at the person’s whole life and where they want to be in five years.
The Misconception of "Motivation"
Stop thinking of coaches as cheerleaders. If a professional athlete or a Fortune 500 exec needs a coach to "motivate" them to work hard, they’ve already lost. Motivation is fickle. It disappears when you’re tired or when it’s raining.
A coach builds systems and habits.
They don't want you to feel "inspired"; they want you to be disciplined. They want your baseline performance on your worst day to be better than your opponent’s performance on their best day. That’s the goal. It’s about raising the floor, not just the ceiling.
Real World Impact: The Data
Look at the numbers. According to a study by the International Coaching Federation (ICF), companies that invest in coaching see a median return on investment of 700%. That’s not because the coach taught them a secret handshake. It’s because the coach stopped the leaders from making stupid, ego-driven mistakes that cost millions.
In the NFL, the difference between a winning and losing season often comes down to "game management"—deciding whether to go for it on 4th down. That’s a coaching decision. It’s math under pressure. If you have a coach who understands probability, you win more. If you have one who coaches by "gut feeling," you eventually get fired.
What Happens When There is No Coach?
Stagnation. It’s almost universal. Even the best in the world, like Tiger Woods or Serena Williams, kept coaches throughout their entire careers. Why? Because you can't see your own back.
Without that external perspective, you start to believe your own hype. You stop correcting the small errors. Slowly, those small errors turn into permanent bad habits. You basically become a "closed system," and closed systems eventually run out of energy and fail.
How to Actually Use a Coach
If you're looking for one or trying to be one, you have to get over the "expert" hurdle. A coach doesn't have to be better than you at the task. They just have to be better than you at analyzing the task.
Start by identifying your "Critical Variable." What is the one thing that, if it changed, would make everything else easier? A good coach will find that in the first twenty minutes. They won't let you talk about the easy stuff. They’ll go straight for the thing you’re avoiding.
Actionable Next Steps
If you want to apply what a coach does to your own life or team, you need to change your perspective on feedback.
- Record everything. You cannot coach what you do not measure. Use video, use spreadsheets, use journals.
- Isolate the variable. Stop trying to "get better" at your whole job. Pick one specific interaction—like how you start a meeting—and coach yourself or your peer on just that.
- Audit the environment. Often, a coach doesn't fix the person; they fix the room. If you’re struggling to focus, it might not be a "you" problem; it might be a "your desk is facing a window with a lot of distractions" problem.
- Ask "What else?" When you think you’ve found the reason for a failure, ask "what else?" three more times. The first answer is usually a surface-level excuse. The fourth answer is usually the truth.
The role is about transformation through observation. It’s a relentless, often thankless process of tweaking the small gears so the big machine can run at full speed. Whether it's sports, business, or just trying to be a better human, the coach is the bridge between "I want to" and "I did."
