Jack was 'bounced off the canvas' countless time before he had enough support to prosper, and he would tell you the same. It's interesting to note how much of a people's person Dempsey really was, no doubt some kind of personality backlash to the animal that hunted his opponents down. Dempsey's 'rough beginnings' were not your average tale. Similar to 'Jersey' Joe's relationship with Felix Bocchicchio, had Dempsey not met Kearn's there is a good chance that the Mauler would have continued to grind his way down a sour path of little food and no opportunity. Kearn's saw sodium in Dempsey, and so he provided the water.
