You are in trouble but if you want to survive you can still probably remain up in your league if that is a priority. However someone has given you horrible advice and the money you have wasted on really bad players will make survival much harder.
The players you are selling are mostly rubbish but Maynard Irons, John Goodwin and Callum Singh have potential as backups if they don't sell. The rest, if they don't sell, don't relist them just fire them after your game on Saturday.
The other urgent issue is Allan Brinkman your future star (and now Łukasz Pochmara who looks like a terrible purchase as well). You must play him 48+ in the scrimmage tonight. My tip for doing it best without screwing things up is play five guys in the scrimmage. Set each one as starter, reserve and backup for one position with the options "strictly folow depth chart" and "let them play" selected.
COMPLEX BUT BEST
I wish I knew their stats so I could give better advice. It would be best to play them both at PG but Pochman already has 48+ at SG this week so maybe best to put Brinkman at the SG position for 48+. If you are keeping Mack Irwin put him at the other guard spot just this once. For training type choose Outside Shooting for SG.
LESS COMPLEX BUT WORSE
Just put Brinkman in for 48+ at PG tonight and choose jump shot for guards and lots of people should get trained. Make sure you have a level four or higher trainer.
STOP SPENDING!
Your money at the start is plentiful and it will be a long time before you have that much again and you have already thrown away a lot.
Your trainer should cost less than $20,000 to buy and have a weekly salary of less than $15,000. If you can get a level four with fitness speciality that is a great bonus.
