The worst thing you can see is someone who does nothing but plays games when they're "training" it's usefull, yeah sure. But there are fundamentals to the game that no matter what level you're playing at you will see people training. Drills like snapping, running and gunning, laning, moving between bunkers, holding someone from making a certain spot and so on.
There's no point throwing yourself into a game without knowing the basics and it's something you see time and time again and without anyone to tell you where you're going wrong the same mistakes will be made. If you want to train more, head to a site, buy a box of paint and spend the day doing a drill that works on part of the list above.
The K-Project teaches fundamentals through online tuition (I think in the form of videos) as well as theory, which is drastically over looked and little understood. It's not just breaking down a field but how to dissect moves and figure out how to best react in situations.
