Dillon showed he is the far superior grappler. Jake won on a technicality in triple overtime.
Jake Shields being called the winner of that grappling match is like if, because there was no finish, in the Joanna vs Andrade fight last saturday at the end of 5 rounds they had to roshambo to decide the winner afterwards, and Andrade wins because she stands back up 8 seconds quicker after they are both kicked in the junk.
Those are the rules, I guess, but no one would consider Andrade the better fighter.
