I agree. I think that Faber will match up better because he is a lot faster than Brown is and that was Brown's biggest downfall in that fight was that Aldo was just way too fast for him.
Not saying that Faber will win or anything. Aldo is an absolute monster. I will definitely be pulling for Faber though if it happens though.
I'm pretty sure his downfall was that he couldn't take Aldo down. Which really doesn't mean anything towards whether or not Faber can since a smaller faster wrestler is a completely different animal to deal with. Faber could possibly outwork Aldo in a 5 rounder if he can score takedowns but I see Aldo finishing him. I'd be really hyped to see that fight though hopefully it happens.
