This game have nothing wrong.
- Your weak OD made you lose the game, even his low game shape he scored you A LOT.
- Also your offensive movement is so weak, you only assist because you have good inside scorers, but not because you have good players on passing.
It's not worth to pay inside players of 50-60k salaries and playing LI if your PG or SG doesnt have more than 6-8 on passing, you are wasting money because his performance are really low. Before buying such players you should invest the money on a PG that will make you play better or if you train rookies, at least buy a PG that is able to play on the SG to make sure he will assist the PF-C.
Don't be confused about the number of your assist, sometimes you can make 15-20 assist even if you have a bad offensive movement, only because you have great scorers or the other team is weak on defenses and another times, having a good offensive movement give only 15, it's not about quantity, it's about the quality of the asist.
