It is a problem and it shouldn't be one of the tactics.
I demoted to 3rd league. I now have the largest arena in Australia, and a very large sum of money in reserves, as well as an ok 2nd league roster (maybe with a minor salary change).
I did this through tanking.
Even though I chose this tactic, I still think it's bad for the game. I think it's better if we focus on, as I've already suggested, basketball strategy not some silly flaw in the game.
It reminds me of some older games I'd play where the AI wasn't intelligent enough to get around an obstacle. Get the AI stuck on the obstacle and you can just kill it using ranged attacks. While this is a good strategy, I would prefer to play a game that is more realistic.
