I hate to say it, but it really seems like JDS is past his prime and on the down-swing of his career. Rothwell on the other hand is on the up-and-up, and if Overeem was able to drop JDS then I'm sure Ben could hurt him with a clean shot as well. I would like to see JDS get back on track but I haven't had much faith in him recently to be honest. I was willing to give him the benefit of the doubt after his... curious performance against Miocic because he underwent knee surgery less than a month after the fight, but he looked completely tentative and weird against Overeem too.
He just doesn't attack with the same urgency and violence that he used to, and he has stopped using the intelligent feinting and set-ups which were responsible for his success in the UFC in the first place. It's a little sad to be honest. JDS's hands actually seem to have gotten worse, not better. Hopefully he can prove me wrong, but I favor Ben in this fight.
