Two vital things for noobs:
1) Make money
2) Train players
Less important is winning games - it comes with the other two.
To make money the first thing you need to do is get profits up and costs down. You have 13 players, you don't need that many. I would suggest sacking or selling about 2.
Victor Lupea (13090791) Point Guard looks like agrbage.
Valter Vidulić (16213814) Center is garbage.
Domenik Ahrendt (16213804) Small Forward is probably garbage.
Anyone who it says on their $ estimate is $10,000 or less should probably be replaced asap.
Next think about your arena prices. It looks like you are putting them up, good. You should have built some extra seats earlier. Maybe build just 2-4 luxury boxes soon.
Training
This is probably number one.
VERY SADLY you sold your most trainable player Jean-Marie den Adel for peanuts yesterday. This is a tragedy.
The only guys you have left who are even remotely trainable are
Connar Bragg (16213813) Point Guard
Weekly salary: $ 3 617
DMI: 9100
Age: 19
Height: 6'3" / 190 cm
Potential: star
Game Shape: average
and
Alan Wall (14844563) Point Guard
Weekly salary: $ 4 299
DMI: 15700
Age: 19
Height: 6'2" / 188 cm
Potential: allstar
Game Shape: respectable
and neither is very exciting.
You need to make some choices.
1) Will you do 1 or 2 position training?
2) what position(s) will you train?
3) Who will you train?
At least Bragg and Wall are both PGs, so maybe you could buy an 18 year old PG off the TL and add him to those guys. It is a start.
You MUST get at least a level 4 trainer. You can easily pick up one with less than a 20k/week salary for 20k or less.
If you respond I will send you some more ideas. Good luck.
