I'm not going to give up. If NBA 2K producers can be passionate and give all them players signature moves and abilities, another company can do the same. A boxing game needs to be deep like MLB The Show and all the true to the sport games.
It's not about individual boxers signings. EA is being too selective or stubborn. I had a list of boxers who wanted to be in the game. They only used 3 out of 25 or more boxers I had.
What EA needs to do is push it's Create A Boxer mode more by upgrading so fans can make accurate boxers.
