They may replace an owner who has got his team deep into the relegation zone with no chance of recovery. Even if he tries his best, he may not be able avoid relegation, and he is told his season ticket holders deserted him for the horrid season, and his draft is bad because he didn't invest in scouting.
because we place owners in the bottom division that has humans, late season replacements cannot be relegated because generally there is no division below them.
Replacement may also cause competitive imbalance as a replaced team suddenly goes from conventional tactics, to a new owner experimenting with 5'8" players, or seeing what happens with CT every single game, or perhaps doesn't bother to set a lineup. It also can be especially unbalancing in the playoffs.
the opposite case is also true... owners drop in the midst of the playoffs and suddenly their tactics go from consistently unconventional to normal. Normal players can also do this strategy.. i know i have. Being unpredictable is fun i think. Diligent scouting will reveal that your opponent has become a human and you should consider the possibilities.
In general I think that getting owners into a real league and into the Buzzerbeater culture as quickly as possible is better than having special cases, which really only make things marginally more fair.
In your proposal, you still have players who enter the league late being at a disadvantage.. and players in the LSL share the same uncertainty about their opponent being human or bot.
I don't see a freshly reset team being a serious challenge to any team that has been around for more than a month... if they are a challenge then the team hasn't been that active, because it is relatively easy to improve your team from where you start to a more competitive place. (please correct me if i'm wrong on this.. but its my impression)
In short it seems like a considerable amount of work (on the same scale as building national teams/private leagues), makes the game more confusing for new users, and has a marginal benefit to game play. If others disagree please chime in.
I hope this doesn't come off too harshly.. we really do appreciate ideas and I think we've accepted a number of them. The draft is definitely an area we have listened to users complain about and are going to be changing next season, but that is my honest assessment. There is another thread about some of the ideas including the one I personally favor... a user set weighting that produces a custom dot product on the players ratings rather than a one size fits all rating.
