I just don't think he should have played differently! He just got edged out of the final three, so his strategy getting there was solid. No matter what he tried, he was going to be perceived as a threat, but his likeability, loyalty, and letting the others take themselves out was a great strategy for him last time. I think he blew it by thinking he needed to do something different. With a secret idol in his pocket, he could have stuck with his original alliance and tried to get the immunities he needed. There was no guarantee he would make final four with the numbskulls anyway.
