At least setting up teams with a somehow competitive roster for their league would do some good. It´s hard enough to start with a bunch of scrubs in a countries 4th or 5th div, now if you don´t have a serious upgraded roster in a top league, you get bored quickly I assume.
Maybe there could be some "initial questions" to determine your roster ... like ... "which position do you like most?", "do you prefer a balanced deep team or a short rotation with one or two team stars", "all offense, best defense in town or just balanced" and maybe "grab all the boards! - go for the highlight reel (steals and blocks)! - distribution! all about distribution" and finally "youth is the key! - the mix will do the tricks! - veterans will do!" which could determine your teams direction to start with.
Of course, when a newbie team of that kind with a "somehow competitive" (read: team salary high enough to compete - on paper - for 6th spot) roster goes bot within the first 3 months, no player at all may go FA, else this would open up too many ways of cheating.
Cheating is a big issue there actually. Maybe even the transfer market should open AFTER at least 4 weeks in game (for selling players), to avoid that and encourage step by step learning and building.
