I'm not convinced fmj at 40 could ever again hang with canelo. His timing would be off, reflexes off and couldn't ever again get physically as fight fit as he was in 13. No win scenerio, stay retired or lose to Spence, canelo and ggg
Did Bow stop being a champ when he threw his in the bin to avoid Lewis? Did Robinson stop being the champ when he said he was "too pretty to fight Burley"
