I think it's dumb to say he's "started fighting timid." He wasn't timid at all against Cruz and he sure as hell wasn't timid in the first round against Werdum. What he was is CAUTIOUS. He got the knock downs on Werdum and didn't want to rush in and be caught like in the second fight with Sylvia. It's obvious from the first round that he's got his killer instinct back; he's just alsio smart enough to avoid staying up close with the #1 HW grapper in the world.
As for his chin, it's still weak. It's exaggerated by some, but you could see him retreat instead of exchanging blows when Werdum went for flurries. I think he knew he could get KOed if he traded punches, so he was looking for the one-shot counterpunch KO. He came close a few times but couldn't quite finish.
