They have already created some realism, by letting the scouts give you different game stats.
The problem with information sharing, is those 3-6 "friends" working together. We want to keep this game fair do we not? Ok let's say in some bizarre way everyone shares info. Depending on the players in draft you can calculate how many teams with how much invested you need in order to receive the whole draft info. Leagues with highly active players will get a huge advantage over those who are all playing for themselves. Or leagues with half bots.
Another example: What happens if your championship rival has 5 friends in the league lower position and every one of them CT-s against you and ties against others etc. No chance to gain HC for the playoffs.
I personally dislike any mutual TIE's, it borderlines cheating + I dislike any requested CT-s aswell (with no apparent gain for the CT-ing team).
If 3-6 friends (i.e. 18.8%-33.3% of a league) can really work this closely together, and stick in the same league for a long time (since the helping wasn't good enough to get any friend promoted), so what? How much of an edge can coordinated draft information really help, assuming it can even be pulled off? I'd see such sharing a sign that BB has a nice community of teams who like to work together, be friendly, etc. It's nice when a league's best team have the opportunity to help the worst teams, as could happen in a draft. But if you don't like mutual TIE's because you think that is borderline cheating (instead of just saying that the TIE system itself is what you don't like), then you just aren't in favor of teams looking for win-win deals. If we could have a system of trading players that was fair, you might be against that, too.
But I think this thread is a lot about wanting to make the draft system itself, which tends to get a lot of criticism, better than what it currently is. In the NBA, players need to register for the draft, so every team sees a list of players available through the draft before the draft begins. NBA teams hire scouts to watch college games and practices, high school games, amateur tournaments, pre-draft workouts, international league games, etc., and get much of their information that. But GMs can also read the newspaper, buy scouting reports, watch games on TV or in person, etc. that before a draft, even a team that has a relatively tiny scouting budget still at least knows the names and some background of the 40 best players registered for the draft. The BB draft is so far away from the way that, so I think before killing an idea because of one or two issues that some people may not be comfortable with, we should focus mainly on trying to find a way around real problems and seeing if there's a way to make a new idea work if we think it could make the game fundamentally better.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
