Good luck. Remember when they fought Cain was coming off a very long layoff, looked rusty as hell, SLOW, and heavier than normal with fat.
JDS really isn't as careful a striker as many of you guys think, he's enormously powerful, but he is COUNTERABLE for a guy with mobility like Cain.
I think this is more a 60 40 for Cain.
Cain is cagey with inside fighting and going for takedowns off of landed punches. He's already very good at putting a fist in a guys face and using that to help set up a takedown.
Cain has to move forward and force JDS to throw something with conviction, he has to let JDS throw his knockout punch, and he needs to use that moment to get him to the ground..
You guys don't see his weakness.
