Gradovich beat Dib twice. People are overrating Dib because of 50 Cent. There is a reason 50 Cent didn't show up with Dib in Macau, he's a bum and knew he would lose. Dib can't punch, has no defensive skills and not that good boxing skills. Dib is horrible and Gradovich is a one dimensional fighter that will get exposed once he steps it up.
I never honestly rated Dib or his carefully-manufactured IBF reign, so while Gradovich is very fun to watch and obviously rose to duty's call to capture the world title on very little experience and then defend it with an instant rematch, it remains to be seen how well he does with truly world class opponents and not just a paper champ with a dirty streak and delusions of being slick and versatile because he managed to outbox some low-grade and shot guys with dubious org rankings. Gradovich vs. Dib I, however, was even wider for Gradovich than what the official scorecards reflected, IMO - and it was encouraging that he stepped on the gas and stopped him in the rematch. I am hopeful that Gradovich is able to put a nice reign together...but the jury is still out as he still has never fought anyone better than Dib on which to base any real analysis.
