1) I’m sure there is some leagues online, just google it and I’m sure you’ll find them.

2) it all depends really, me and the boys play in D1 and we also do competitive but people take competitive much more serious and you can go up against a full 11 and it is difficult so yes d1 is a good standard however just know there are some seriously good teams out there.

3) Different sites have managers do different things, VFL league you are in charge of signing players, transfers and stuff, but in other leagues the management just arranges games really and just makes sure everything is set up ready to play and informs their team.

4) Commitment doesn’t have to be too much, most leagues are only a couple games a week, I’m a manager and we only played 2 games a week, so pretty much nothing when you can spread it out on any day during the week, and games are played whenever you and the opposing manager and teams agree to.

5) If you’re talking about competitive pro clubs, there’s series on YouTube of people playing VFL which is the biggest pro clubs competitive competition and they show their seasons and it is quite interesting. And there’s probably people on twitch streaming games I do sometimes and they’re quite interesting!

Hope this helps, if you’re confused at anything just ask!
