My big problem was I spent my cash reserve to make the push. I think I am going to train him, and upgrade my trainer as well this season. I can also round out my bigs a little more. I will accept the fact I will relegate, and hopefully pick up another good draftee. It might also give me the chance to stockpile some more cash.
Your call on what you do with Donny. But if you sell him, you should be able to replenish your bank account easily.
If training him, sell some other guys to raise enough cash to buy someone else to train along side him in other matches to form a killer back court down the road.
