You should win easily but try to get some bench involved like others have said. You have the home court advantage so I think you will win even if you play PO normal. That will give you some kick to semifinals. You have by far the best starting 5 but your game shape management doesn't exist. If you play your best players 48 minutes a game you won't get results you want to have.
Conclusions:
- Get your bench involved
- Substitutions: Let coach decide
- Foul Trouble: Sit them
- Enthusiasm: PO Normal
- Try to get your main players between 60-70 minutes
- Acquire a couple of players for your scrimmage game to even up minutes
- Your new acquisitions won't get paid until the next season, so don't worry about their salaries...
- Your best players should have GS between respectable-proficient
- ...then you don't have to worry about the bot clean-up
