I don't know what the point of that comment was -- I'm not being snarky, I'm serious yo.
Anyway, Rashad, Davis, Rampage, Shogun, Jones, and even Thiago Silva are all more dangerous than the majority of the opponents Anderson has faced. Mousasi as well, although Dan Henderson might have something to say about that. Hell, even Bader, Couture, Ortiz, and Greco (at least at the time he fought him) would give Anderson problems.
You give Lyoto all of Anderson's opponents and he beats and/or smashes them all, minus Weidman, and Lyoto fared exponentially better against him than Anderson, and that is not remotely debatable.
Pretty simple.
