Sounds odd, but if Zab is confident he'll win then it might not be a bad move. When you think about it there aren't to many fights out there in which Judah can be paid well anymore, and he'd be stupid to fight Khan again should be get the title back. Judah vs Peterson would still be a fun fight imo, and would probably be pretty easy to put together. I imagine Judah is just buying himself some time and seeing how that all pans out.
