You can consider both in whatever proportion you wish. Eg. If we were talking welter weights and included ONLY resume, then Pac would be clearly at the top of the currently active list. If you considered Head-to-head, a lot of folks would have Spence and Crawford ahead of him. Imagine you are in charge of the Transnational Boxing Rankings or the RING rankings. What would your top five heavyweights list look like ?
