To be fair, Ottke didn't want to fight him. A fight with Carl would have been nice, but Carl hadn't done a lot by the time Joe had hung up the gloves.
It's true that Bernard doubled his demands. But I think there was more to it than him just deliberately throwing a spanner in the works to prevent the fight from happening. There's some interesting links online that give details of Bernard's contract and his dealings with Don King and Showtime that played a part in proceedings. Joe never wanted to get Roy into the ring when Roy was anywhere near his prime. Don't be fooled.
He should have moved up to LHW instead of staying at SMW after he knew Ottke wouldn't fight him. Bernard never needed to travel. Joe did to enhance his reputation and his resume earlier.
That's a big claim considering GG isn't a big guy and we've never even seen him at SMW yet. You think Carl would have beaten Joe?
