I’d have to make quarry the favorite based on resume but this might be a very hard fight. As limited as Ibragimov was, he wasn’t the type of fighter who would likely walk into Jerry’s counters. In fact he often tried to be more evasive rather than come-forward.
Not going to be popular on the classic forum but I like Sultan. I'm huge fan of Quarry but stylistically Sultan is a bad matchup for him. If he doesn't get stopped on cuts he drops a decision. Sultan was a very smart fighter with a long and successful amateur background. Not too many guys like Sultan back in Quarry's era.
