Yes I think he would take him down and do mean things
But you have to admit Rua would have a punchers chance...maybe even a high kick could land(rocked Gillante with one)
Shogun throws very heavy strikes
I give shogun 10-15% chance of KO...85% chance of DC grinding him up
I would love if Shogun steps in for a DC opponent on late notice so DC couldn't watch as much tape on shoguns Heavy leads and Heavy counters...In my dreams(Pit3744) I see Shogun landing that nnnnnnasty uppercut on a shooting DC and finishing with the hammerfists of doom he often uses.
