Silva was the same fighter against Weidman, he was focused, clearly wanted to win and tried everything in his bag of tricks to get Weidman to make a mistake. I'm referring to your first post which mentions that Silva has not been focused or hungry in over 7 years because the exact opposite is true about your statement.
Anderson lost to a more focus and hunger fighters. I'm saying he lost that focused/hunger at some point in those seven years. He lost, the rematch will paint a story for the rest remainder of his career. You can't tell me he was 100% mentally focus for this fight when a larger portion of the media leading up to this fight was bringing up superfights.
That lost either could be the end of a legend or the begin to a new path of his legendary career. He could end up like gsp after serra or end up like Fedor.
