Re: Froch/Mack, DeMarco/Broner & Viloria/Marquez RbR!
Yafai's situation is something which I think Joshua should take heed of. Kal had been fighting the top amateurs for a long time before he turned over and it tells, he's a class above all these journeyman and isn't even getting rounds from them. He is at Commonwealth/British level already in truth.
I think if Joshua stayed AM til Rio, he'd be similar if not better. His raw talent would be best nurtured against top amateurs for a few years IMO rather than turning pro and having a couple of years fighting nobodies. There's no need to rush.
(I realise that I've gone off on a tangent haha)
