lets face it, 1st fight was an absolute fluke. he beat a ring rusted cain which had a long layoff coming back from a big injury.
No, that's a stretch. JDS caught Cain like he caught many. If Cain didn't come with a different game in the second, he probably would get caught again, but smartly, he evolved where JDS did not. Cain proved to be the best twice now, but you don't say a KO victory of a KO artist in JDS was a fluke, please.
