The sidekick scenario only happens once. I use it as a benchmark for when to ask my GM to trade my teammate. You could ask for the best player on your new team to be traded. That is always an option, at least every other GM conversation. Idk what happens because I havent tried it. But hypothetically if youe favorite team shows the most interest in you on the trade interest list then they should trade for you. Hypothetically, again I havent tried that. If you try that tell us what happens so we can further understand this whole trade process.
