I agree that those excuses you posted first are all bullshit. Anderson wanted to win the fight, age has not caught up with him, Weidman to a degree was lucky but luck DOES play a valid factor in fights (he threw a nice punch and it landed).
But to me, Weidman's win was only big on paper.
I didn't see ANYTHING from Weidman that was different and more impressive than before really.
Weidman's punch after flooring Anderson was killer, so I think his ability to finish a fight after hurting a fighter must be really good.
The downsides are more so though. His temperament proves to be VERY weak. He got Anderson down and nearly locked in a sub. Then Anderson clowns him and he wants to keep it standing? TERRIBLE decision. I was really unimpressed by that aspect. Also, Anderson was able to somewhat defend some of his takedowns, which is actually a point that Anderson is VERY weak in, and I feel people overrate his BJJ and TDD a lot. Lastly, Weidman's inability to check even simplistic leg kicks would put him in serious trouble against someone who could capitalize.
I still feel he's overrated and has a lot to learn. I'm still not on the hype train just yet. I do feel he'd win a rematch by being MUCH more clever and focusing on the takedowns a lot more, and I think he might do really well if he keeps growing every fight. But to say he's def going to hold the belt for a long time or that his name is up there with the best is way too premature to me. I think he has trouble with Bisping (although wins by KO) and loses to Sonnen and Belfort.
