I guess the best comparison would be. There are muscians that are experts at playing their instrument, and are very technical. Can read music sheets ect.
But ask these type of musicans to just freestyle or add-lib something without sheet music in front of them, and most of them couldn't do it.
Then get a guy like Jim Hendrix, who played his instrument up-side down, couldn't read sheet music if his life depended on it, but was able to do things with his guitar that nobody else could do. Come up with riffs and numbers out of thin air and just freestyled.
Or BB King. He had small fingers that couldn't reach the threads, so he created a slide kind of guitar playing where he slid his hands across the threads.
That's kind of what I'm talking about as far as American and Euro fighters.
