Jorge was never that good. He had trouble in the UFC before. He left and racked up wins vs. average to well below average fighters. He got ranked because he had a lot of wins in a row. He came to the UFC and got dismantled and kicked out of any rankings.
He has some skill. But it doesn't translate well to big boy MMA. He gets KO'd quite easily. He has some sneaky submissions but that won't be a factor vs. Gunnar.
Gunnar should roll here.
