How knowledgable do you think the following users are?

i think 90% of the users on here are not over 20, and while they love the game and their team, dont know much about the intricate parts of the game, eg, players running unders/overs lines(they dont know what they are), out and in /pes, full rules, all players in all teams, dont see off the ball work from players, things like that to name a few, but the other 10% are very knowledgable and seem to understand more than the star players and just knowing what a try is and knowing when there team wins or loses
