I agree with you, before Casimero became popular, Rigondeaux has already become a champion and he was also winning good fights, things just change when he loses against Lomachenko, but we can understand since Lomachenko is the favorite.
if we compare Lomachenko and Casimero, Lomachenko is a world-class fighter which I think everyone knows compared to Casimero, so Rigondeaux definitely has a shot here, but I'll definitely bet on the young and hungry fighter who is Casimero.
Lomachenko is a way different level fighter that is for sure, but we may never know if they will had a rematch, and that is the only lost Rigondeaux had and 1 No Contest let's see if John Riel Casimero really can out speed Rigondeaux,
Yes, he has a shot, but Casimero will hit him and he will become defensive again, that could make the fight boring for us.
I don't think that this fight will go boring, that superb power punch and accuracy of Rigondeaux will be his weapon while Casimero has the speed and power in my opinion this is definitely a very exciting match I could not see the full depth of what may happen means it is unpredictable.
