The problems i see in the future of the game is the teams that have been around for a long time are going to absolutely smash new teams already.
I mean the teams that are set up well now are beating other teams 130-90 and scores like this. These teams are pretty similar and should be beating each other by a lot less. If more advantages for older teams were introduced it would make the difference between new and old teams even bigger.
But I do see the logic behind having a team chemistry. If it did exist I would suggest something that is achieved within one or two games if the players are the same. This way the bigger teams in the future who are buying and trading players will just lose this "chemistry" and the newer teams are the ones who have the advantage.
