Lawler may have caught a guy but Babalu got straight out dominated by a better fighter.
I went back and watched babalu mousasi again (didn't take long) and I just don't see the same fight you do. Babalu escaped side control and created a scramble, mousasi popped up and unloaded on him. An inch here , a fraction of a second there and the fight would have lasted longer. At their level that's all it takes on "any given night". Mousasi fought well and won. He didn't dominate or out class babalu.
I also came accross this fight while I was looking. To me, this is what out classed looks like.
Using their almost common opponents and my majic mma math matrix, I predict Robbie gets choke out in the second round and babalu doesn't let go until Matt Hughes soccer kicks him in the head.
I'm betting the house.
