Ace is an incredible fighter and a perfect poster boy for Dana white, so white would know to protect him from the beating Rua would give him. Isn't Rua in a heavier weight class though? Machida beat the crap out of Franklin, so would Rua. Sorry Ace, but your heart and grit ain't enough to beat Rua. Not to mention, who was the toughest guy Franklin ever beat? Evan Tanner, Loiseau, Quarry? Great fighters, but nothing compared to Rua. A better question would be Liddell vs. Nogueira? Although Nogueira probably has 30 lbs on Liddell...not too fair.
