I was going to make a similar comment but take it a different direction. With sports, just like with music or anything else, you need to understand the context and reasoning behind skills training. A lot of people -- for example, playground ballers -- are awesome basketball players, but they're awesome at 1-on-1 and if you throw them into a structured, officiated game they'll contribute far below their raw abilities. Football is probably even more extreme. With anything, you need to practice & study with intent, and with almost everything, having a coach/teacher/mentor/guide makes this much, much easier.
