I will pass on the Avs lotto, let others that want it more have them.
My suggestions:
As for the draft, 4 rounds should be about right. After that, it usually turns into autopicks galore anyhow.
And trading picks....only trade up to 4th round, but include 2019 picks. When we do the grading, we have to list the 2019 picks left to each.
Also for grading at the end, I would suggest categories. Best win now, best steady build, best tear down, and most improved. This may not be feasible, but folks might like some recognition for taking a team like LA that seems to be in trouble and blowing it up for a rebuild, even though that would preclude them from being a contender for the "playoffs."
Maybe also one off winners. Best trade, biggest draft steal, etc.
$80M cap, 21+2 rosters, committee rules on NTC/NMC waivers and RFA/UFA signings. Or could do it as 5+ upvotes (post likes by registered players) for each of those. Unbalanced trade vetoes nominated by at least 3 registered players, then either it goes to committee or one of the folks running it makes a post for it, and if that post fails to get 10? "registered" likes in 24 hours, the trade is cancelled.
That's enough crazy ideas from me for now.
