Thanks for your messages!
To the first one - I didn't realize you're such an experienced and apparently very knowledgeable manager, so therefore I crowded the forum with mainly basic tips. But maybe, just maybe, someone will get something out of them. Maybe not, but that's life. ;P
As for BBHG league, frankly I'm completely unaware of possible discussion about it that takes place out of Buzzerbeater forums as I don't use Discord. As you can see, what becomes to BBHG league it's been somewhat silent here in the forums lately. If you or anyone else happens to know if discussion about it has taken place in Discord, please let me know.
As it stands right now - and like you already noticed by reading through the thread - there are 8 of us currently interested in participating in the league.
What becomes to amount of interested teams, the current number (8) is already quite nice, and on the other hand I'm somewhat disappointed that there still aren't more of us (as there are actually even some more HG teams in BB than the list at the 1st page of this thread mentions). Having said that, it's more important to have dedicated teams to participate, than having plenty of teams that wouldn't be willing to take the trouble to follow through with their obligations to the BBHG league (for instance, to arrange weekly matches as planned).
Like I mentioned couple of times before, nothing would restrict us to begin the league as soon as we want, as already that amount of teams would be quite decent. Perhaps not optimal (as some tough decisions would need to be made when deciding what kind of league system to use and how many would qualify for playoffs, or then all 8 teams would need to be granted a spot for playoffs, which on the other hand would make regular season a bit less meaningful...like you can see with this one example only, there are so many considerations to be made to make it optimal... having said that, optimal is a relative term and sometimes it's just better to get things rolling anyway instead of waiting for everything to be "optimal").
I have presented few of the possible (of practically tens of possible) league systems here in the forum, but apart from Elan Demars' manager demars, not many remarks/comments have been made about them. So I have no idea if participating teams would for instance prefer the most traditional possible league system, or rather more inventive/interesting one.
As for BB staff/owners interest of taking an administrative role of this BuzzerBeater Homegrown-league, I honestly don't have any clue about that. Like I mentioned/hinted in this forum multiple times (I believe), I wouldn´t mind see BB owners taking control/administrative role here, as it would free of us of lot of manual work (most work would fall to the league commissioner though, so not that big of a task for a regular team that decides to participate!) and would ensure everything goes as planned within the planned envelope time wise. So I don't know if BB owners even read this thread as I haven't had any personal BB-mail from them about it, and as you can see AFAIK they haven't commented anything to this thread either.
So to your question 1): mentally we are closer to establishing the league, as personally I keep entertaining different possibilities (in terms of league systems, awakening more interest towards the league, etc.) and thinking what could be made to make the league as good, interesting and fair to all as ever possible.
Also, a full set of rules for the BBHG are still to be established.
Firstly, if we keep this league "on our hands", I think we need to have some sanctions/penalties if you don't stick with the rules (sanctions could differ from one type of violation to another).
Second, I guess many "typical real life rules" would suit this BBHG league well, however I'd like to see couple of additions. We could for instance consider changing the regular season team rankings determining order slightly, etc..
