He should move if he can't make the weight. I remember during the first fight, he was off in the first try. Although me made the weight in the second fight, he seems to be very dry and lean.
That might be his next move because he can't really defeat Haney or at least give him a hard time. That way, he won't be having some struggles in his weight if he indeed have some issues woth it and it's no use in staying the same division if he can't be a star.
Kambosos' problem is Haney himself. Kambosos was undefeated before confronted with Haney's boxing strategies. Haney seemed to be Kambosos' kryptonite. Kambosos was strong. He even defeated Teofimo Lopez. It's just that boxers have different strategies. Haney was more like Mayweather. And that's something Kambosos' found hard to solve. He was a puzzle Kambosos really failed to solve. He doesn't necessarily have to go up in weight though.
Those 2 losses from Haney is just the beginning, he only had 20 fights, and those 2 losses of him will make his opponent so confident in betting on him. usually, when a fighter had losses already, he is not the same anymore, just like what happened to Bronner, he was once undefeated but when he experience a lose, that continues to happen until he losses his career.
It could be just I think Kambosos will have to make a difficult decision to whether go up in weight or stay in this division and continue to campaign and fought some notable fighters again.
Broner case is different though because he is so arrogant and brandish that's why his mentality went down after he lost to Maidana and up to know he thinks he won the fight against Manny Pacquiao. LOL.
Kambosos should fight a boxer next that he can beat and bring back his confidence.
