Strategy: Get good.
For real, though. In real life basketball if a team has great shooters and no big men with any good skills what would you do? You would put more pressure on the guards that probably have to slow the ball down for their bigs. Outside/Slow. What do you do to a team that has amazing bigs and subpar guards? Inside. What about a team that likes to run as fast as they can and scores with bigs and guards? Neutral/Fast.
The guessing isn't really guessing. It's planning for your opponent. Imagine that it is your players planning for specific plays/sets the other team is running, just like what happens in real life.
Rather than claim a particular part of the game is unfair, why not do better at what you have 100% control? Expand your arena, don't have your best players over 35, and get some 18-20 y/o players to train and improve your team from within. Your team has more to improve than what offense they get wrecked in.
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.
