Dinu will shock the world. I hope. He has the skills to pull it off but will probably quit as soon as the going gets tough.
There isn't anyone who Frank could fork out money to get unless he goes through top rank so maybe Takam or Forrest.
Ajagba or Fedosov (recharges coming off the Medzhidov KO) I think both will be chomping at the bit to fight him, unlike the top 10.
I think it's a multi-year rebuild for him. His power isn't enough to bail out his apparently low ring IQ. Even if he looks good against Dinu, not a sure thing, there's no rush and a lot of risk.
Not a bad shout. Warren would have to pay silly money to Don King similar to what Hearn did for Chalres Martin as King knows DDD would be massive favourite. Depends if Warren values the regular belt for amount of money that King will be asking for it.
