Steph obviously doesn't have a prenup, and that woman wants out. I understand feelings and history and the kids and all that, and I'm not gonna call Steph a simp but he's obviously one of those dudes that's kinda soft and lets his woman run everything.
I'd let her take half, and go on out there and ruin her fukkin self, because that's all she'd do. And whatever the financial planners, lawyers, and accountants don't eventually take, a strong succession of young fly nikkas will. I guarantee you they will relieve her of the rest. Steph is universally beloved. He'll be making multi-million dollar deals long after he's done playing, so he'll get it all back.
I'd bet good money when the streets his wife is longing for so badly is done with her she'll be like Sharon Stone at the end of fukkin Casino. Just left with a couple hundred bucks in antique coins.
