While Betulio played second man to the best of his era, I don't think Chitalada compares favourably to Oba, Canto and Bus Stop. Betulio's educated pressure and head-movement should serve to let him get inside and crowd Chitalada enough to win rounds IMO. Sot was good, but no Canto in the footwork department. I don't think he'd be able to slip all of Betulio's punches. The styles definitively favour Gonzalez IMO, in a case of the squat pressure fighter vs the flashy out-boxer. Betulio close decision, for mine.
