Let's hope this is the first step in Beterbiev's revival. His promoter was a big setback. I hope he will be active from now on.
Yes. Hopefully Top Rank complete signing him, they will keep him active and get him better opponents at least.
Not really, winning it gives Beterbiev a title shot next. It's the logical fight, and actually Koelling is quite a decent fighter.
He becomes Ward's IBF mandatory. The IBF is very strict on their rules, so either Ward will have to fight Beterbiev in 2018 or vacate the title and Beterbiev will fight for the vacant belt.
Possibly, although Skoglund is in the WBSS and already declined a Beterbiev fight twice. More likely, IMHO, is Beterbiev vs Kovalev or Browne.
