How has it morphed?
Whoa! You're kidding, right? How about the most recent change, that at the start of Season 31 a major change took place in the FA system? How about that the original description of the change was so vague that most people thought there would finally be some relief, a better supply of free agents and a corresponding improvement in the economy as relates to FA's, the transfer market and the entire basketball mechanism? How about that exactly the opposite happened, and we found out the hard way why the original description was so obscure and misleading? How about that when Marin was asked about it, he said it was deliberately done specifically to reward training by making training more profitable?
When the game is deliberately changed by the powers that be to reward training at the cost of damaging the basketball mechanisms and wildly inflating the player economy, I'd call that "morphed," and I don't actually think anyone has forgotten that yet, present company included.
So if the free agency changes were immediately (hell, even retroactively) removed, would this change it from a "strange training exercise" to a "basketball management sim"? I call bull.
Before the changes, you could train players, or not. You could buy players, or not. There were some players who went into free agency, and some who didn't. You could invest in the draft or not. You could use GDP or not. You could use the same tactic over and over or not. You could build your arena or not.
Now, the only change is different players reach free agency. Period. The game has not morphed into something entirely different. And it's the smallest component of all of them - free agency is dwarfed by regular transfers, and training and the draft are available to everyone as well.
Perhaps you want a New York Knicks themed basketball sim, where every team is built exclusively through free agency, and if I come across one, I'll let you know.
