Many players asking What specific things factor into the chemistry rating? How do I keep it high? There isn’t much materials on this subject online. So, today, I am going to share with you some personal ideas from my own experience for your reference. If you disagree, just ignore it.

 
 

What’s the influence of Team Chemistry in NBA 2K19 MyCareer?
 
In my experience, with high team chemistry, teammates will pass the ball to you more often when you call for it. They are also most likely to shoot off your passes, as where with lower chemistry they will pass if the shot is slightly contested or there is someone else open. In addition, you win games a lot more and your teammates are generally less retarded if your team chemistry is at ~100%
 
Top positive influences:

1. Winning games
2.  Keeping the same players together
3. Setting your training to work on Team Chemistry (best for older players)
 
One negative influence to chemistry is having a problematic player who is very unhappy. If somebody is pissed off at you cause they aren't getting enough minutes, it's worth taking the temporary chemistry hit to trade him for an older benchwarmer. You can then put the veteran to train for team chemistry and recoup the loss in soon enough.
 
How to increase team chemistry in NBA 2K 19 MyCareer?
 
Focus training on chemistry. Keep your team together, or at least your main core. It’ll come over time. Keep the same players together. It is easier to cooperate well with similar players.
 
Setting your training to work on Team Chemistry (best for older players) One of the negative influences to chemistry is having a problematic player who is very unhappy. If some players are pissed off at you for they don’t get enough time, it would be better to take the temporary chemistry hit to trade him for an older benchwarmer. In other words, you can choose the veteran players to participate in the training, and then the loss will be recouped in soon.
 
There are GM Upgrades that help Team Chemistry. Other than that, you players are supposed to try your best to keep your guys happy (trades always decrease chemistry), and if your team is winning, your chemistry will rise.
 
Try to always get that A+ teammate grade and choose the 'nice' answer in interviews. To upgrade players quickly, you can come to Rvgm.com for Cheap NBA 2K19 VC. It will gets you pretty fast to really high teammate chemistry. It seems to stay there now which might be a limitation of coach and roster like in MyTeam (or not).
 
Other than that, I think you just have to try to keep your guys happy (trades always decrease chemistry), and if your team is winning, your chemistry will rise.
 
Example, if in one of the post-game interviews they ask for a comment regarding how many points you got, tell them you couldn't have done it without your team.
 
That's what builds team chemistry the most IIRC. In addition, pick and roll every play and feed the open man. Make smart passes and limit turnovers, defensive breakdowns, fouls, etc.
