I'm starting a new career as Barrera on GOAT mode and must admit that I am finding it much harder to score knockouts. I'm 8-0 so far with only 1 KO to my name. I stun the opponents all the time and sometimes score flash knockdowns, but I always seem to go to the cards. I much prefer the difficulty levels on this game as the other ones were far too easy, but I would like more stoppages.
