Whats your beef with Weidman? He still doesn't have the tract record to feel like a bonafide champ, but has survived past some killers - and deserves his position.
Weidman at this point in time is legit - maybe not better then Silva in his prime, but better then Silva in his decline. I believe Weidman has proved himself, he can take punch, shows composure and imposes his will on opponents. He is also has been improving, and has the champion mind state (that mental edge, and experience fighting in the spotlight and pressure is worth points).
