Yes, there are exceptions. There are some very talented players with big egos who don't listen to anybody.
But for the most part, I've found that usually the better the player, the more coachable they are.
"Coachable" - able to be coached.
1. Wanting to be coached - open to listening and trying your way
2. Being able to listen to the instruction, and then actually do it!
3. Not just taking the advice and doing it once and then forgetting about it and going back to old habits, but taking the advice 100% to heart, and doing it until it becomes second nature.
I was lucky enough to do a skills session for Ben Simmons (NBA prospect) and a couple of other guys (also pretty darn good players) when I was doing some volunteer coaching at Box Hill Senior Secondary College. It was one of the few times where I actually felt a little intimidated and wasn't sure how they would take me, or whether they would even listen.
They basically had no idea who I was, and even though they were all still at school some looked older than me, as those giant basketball-ing guys often do!
Boy, did they listen! And boy did they want to be coached. They were some of the most, if not the most attentive and most coachable players I've worked with. Every time I spoke or demonstrated something they had their eyes glued on me like hawks. They didn't want to miss a word.
And the most coachable of all of them - Ben Simmons.
You see, great players understand that even though they are good, they could be so much better. Average players think they are good, and can't get or don't need to get any better.
Great players see a coach who might have no idea what he's talking about, and think "I'm gonna listen to every single word he says, in case he gives me one valuable teaching point I can use to improve 1%".
Average players see a coach who is known as a good coach, then think he's an idiot and tune out because they think they know better, because he said one thing they disagreed with.
You can never stop improving. Kobe, Lebron, Jordan got better every year. Every year, they worked on their game and added something. If they still have improvement left in them, surely you do too!
