Those fights being flukes is the biggest myth I've ever seen on these forums.
First fight Anderson was losing the standup and the grappling. Out of desperation he goes into super troll mode to try to get Weidman to stand and trade, and promptly gets ktfo.
Second fight he is again losing everywhere, and decides to throw a full power kick when his leg is already injured, and with no setup.
He lost every second of every round of both fights, and both finishes were the result of mistakes he made out of desperation. Nothing flukey about that. To hear Andy fans tell it, he was beating his ass and slipped on a banana peel.
