Has he ever shown anything like that before? 912 total punches ! Every time I remember watching him in the past he'd start quite fast then limit his punches and coast to decision losing some later rounds.
His workrate was similar against Saunders in the 2nd half of heir match, even though only about a fourth of his shots landed clean.
One thing I have noticed is that being born poor and on the streets does not in fact make you any tougher than the middle class kid in the other district. Both Chris and Conor had soft upbringings, Conor had a jacuzzi in his room as a kid and Chris went to a private school in Brighton. No one could accuse either of them of lacking grit or determination though - not after Saturday. I have seen that 12th round a few times now and it exhausts me just watching it.
