I enjoyed using Shane Carwin to knock out Roy Nelson, knock some of the wind out of his sails that's for sure. Using Marcus Jones to deck Brandon Schaub was pretty fun too.

submitting a gassed GSP online with BJ Penn and I never landed a strike....submitted him from the bottom with a leg choke.....

Knocking out Rashad Evans advanced comp with Rampage Jackson in 2:31 minutes with one elbow... 
Worst was when my fighter in career got knocked out by Brandon Vera getting up from a takedown... Broke my 9 win streak...

Either: 
my Vitor Belfort KO on my friend (A Silva) late in the 4th, it had been a war of jabs for the first 2 rounds, 3rd round a little scrappier and i got rocked from a few knees in clinch, in the 4th he started attacking more because he rocked me earlier, and i kept dodging and jabbing and softening him up, late in the round he flying kneed and I quickly stepped aside and threw a lighting fast left hook. Ko :D 
 or 
I was Akiyama and my friend was Bisping, he had been beating me to the punch all through the first round and jabbing me out, he missed and I took him down in the second, beat him up with knees to the body and hooks from side control and he goes for an armbar, I get out, realise it's dangerous and got up...I step past a superman punch and take down, I got back side control now and i get both hooks, and choke him out.
