There are alot of questions right now. I didn't see any boxer stats on that page. Height, Weight, hand, etc.
I saw a box that said contract. Hopefully you get to choose your fights and scout opponents.
If there are a total of 80 boxers, that will greatly reduce replayability. That would mean that there is either only one class, heavyweight, that you can play or all the divisions have a serious lack of boxers in there.
Time will tell, but it leaves alot of questions.
