Before anything else I would say that your chances of promoting are slim to none. The first place team in your conference is far and away the best team from your side so just making the championship game is next to impossible this year.
On the bright side of things, you look like you're handling GS fairly well, but you can still improve on it(we all can). That, coupled with enthusiasm and figuring out tactics to use on different teams, should be all you really need for promotion from D.V. next year. Use the rest of the season to continue getting a feel for the game. Maybe you will even get a decent draftee to start training. I would say for right now though you should at least be doing 2 position training for your PF and C since they have good potentials and aren't anywhere near being capped, and this would make them better players for you next year when you have a full season to make a run at promotion.
One more thing, build your arena! This will help you get more money once you do promote. More money leads to better players and better staff, which *should* leads to more wins, which leads to more money, etc.
Good luck!
I have 1757 players for sale and I'm $25,835,360 in debt. Buy them at outrageous prices, or be selfish and make me go bankrupt. You decide, BB.
