Out of curiosity, who would you nominate for the title if not Ken?
Ken's submission ability exceeded the submission abilities of those three combined and by a considerably greater margin than those three's TD abilities exceeded Ken's.
Gorgeous sequence there with Ken going from palm strikes to Thai knees to a huge body lock TD. He hits another throw on Yanagisawa at 3:40.
Slick little sequence with Funaki in on a single and Ken defending and then seizing an ankle pick.
Here he controls Inagaki and brings him down hard with a powerful mat return. Incidentally, Ken's control of his opponents' upper bodies and his combination of strength and technique with body lock TDs and mat returns is virtually second-to-none, especially as far as HW fighters are concerned.
And here he catches Mo coming forward and hits a beautiful double.
He may not have been a decorated collegiate/Olympic wrestler, but his wrestling was legit all the same. When you add his submission game on top of that, who else could possibly challenge him for the title?
Who are you talking about here? Who do you think would make Ken look like an amateur on the mat?
