Well I think the reasoning there (and Dana alluded to it) is getting caught (or losing a close decision as we saw a few times at 155) warrants a rematch sooner than getting thoroughly dominated for 25 minutes. Close decision is obvious, but even with getting caught, there's always the question of, well maybe this would've gone entirely differently if not for that one punch landing just right. No one has those questions after this fight. The only thing you could wonder is what if JDS landed a bomb in the perfect spot again. JDS didn't lose because of a split second where he got caught, he lost because he was completely outclassed for 25 minutes and had absolutely no answers. It takes time to earn a rematch after that.
