OK let's see now. NBA superstar's wife is cheating on him for years. NBA superstar also had a college buddy that became his posse and received free housing in return. NBA superstar finally gets a clue and hires a PD to get evidence for the coming legal battle, then files for divorce.
Now, the wife comes back with a story that the NBA superstar actually had a romantic and sexual relationship with his buddy.
Do we conclude:
(a) The wife's story is true. OMG, look at how the NBA superstar behaves. CAN'T YOU SEE IT?
(b) The wife is in a giant hole of trouble, and about to lose everything including her children, being left with only what the pre-nup offered. She wants more, and she wants her kids. So, she gins up stories about her husband, to give her at least a little more leverage.
Hmmmm.... let's see................. what is more likely?
