That fight only lasted 64 seconds.. Cain had one half arsed attempt at a single (I think it was a single, haven't watched in a little while) before he got caught. I don't doubt that Cain can get JDS down.
I also think Cain poses a bigger threat on the feet than most believe, before the KO he was looking good and had outlanded Junior.
I just really think that 64 seconds isn't long enough to judge the two fighters, yeah JDS dropped Cain fiercely, but Cain landed a decent shot on JDS during a combo with a lowkick from memory, as long as both fighters land solid shots, either has the ability to flash KO the other. They are HWs afterall.
Maybe it's fanboyism
, but yeah I definitely see Cain dragging JDS to the mat and beating him to a bloody pulp.
