@WOSdrummer99 responded well. You stated nothing can be instilled in an athlete. So, why have coaches? Just let the students go play on their own. They either got it or they don't got it. Right?! Of course this would be folly thinking.
Let's look at the QB at Barbers Hill that was "suppose" to have excellent potential. Well, that never panned out. Was it because, as you would believe, that he's not really that good? Or, as I would say, his coaching let him down. I wonder how he could of progressed if he had Scott Surrett as his coach? How about Tim Buchanan from Aledo. Or how about Todd Dodge as his coach? You think he could have benefitted from any of these? Or would you still think, you either got it or you don't?
You think when Thompson left WOS, all of a sudden all the talent left? When Thompson left, I wonder what WOS would have looked like if WOS had PNG's coaching staff. I'm thinking between then and now probably a State Championship.
