My first thought was that Mamertas Muchametzianovas would be your best bet to make some cash, but that pitiful rebounding hurts a lot. I'm by no means an expert so this will not be optimal, but what I'd do:
- Drop your costs by dumping some of your higher salary players with poor skill/potential.
- Use some of that cash for draft scouting ($10k? not sure what your cash situation is)
- See if you can find some 18 year old trainees with decent skill. Don't worry about pulling MVP potential, but stay away from the lower end too (bench warmer, 6th man, etc)
- Grab a level 4 trainer when your cash position allows it (assuming you don't have one already)
Based on your team at this time, I'd probably focus on the big men. Muchametzianovas, Ledbetter, Vartnieks primarily, although an 18 year old trainee would be better. Given your trainees, I'd start on rebounding. Get 5 guys 48+ minutes (use strictly follow depth chart) via friendly.
So I expect you would train your current guys up a bit and sell them off. Take the money and buy some good trainees. If you draft a monster in the offseason that could sell for $1 million or more, consider selling him. On the next batch of trainees, expect to sell a couple, keep a couple. With the money you have then, pick up new trainees and branch out into some good guards. I'd consider this a very rough 3 - 4 season plan.
Hopefully you'll get some other opinions that are better than mine :)
