Silva's win was sketchy.
You can play a serious "what if" game with the Silva / Lutter fight - Lutter cut 20lbs to make weight for the fight, and had to cut even more after he botched the weigh-in, so he was weak and unable to perform to standard. Since he actually was able to take Silva down, and was able to pass to side and mount, the question can be speculated on: did Lutter, assuming he had had a better training regimen, have a chance?
But's that's not why I think Silva's win was sketchy.
Silva's win was sketchy because he used 3 clearly illegal elbow strikes to make Lutter tap. He struck Lutter on the crown of the skull with the point of his elbow - very clearly a breach of:
10. Striking downward using the point of the elbow.
Regardless of Herb Dean not calling it, regardless of Mike Goldberg making excuses for it, and regardless of Joe Rogan being a doofus on air questioning Couture about it (Couture himself immediately bringing up the elbows when Lutter tapped), Silva used an illegal strike, and there should have been a time-out to allow Lutter to recover, the same as with an accidental kick in the groin. But seeing as how Silva did it intentionally, disqualification shouldn't have been ruled out.
I sense I'm going to take some heat for this, but that's life. The elbows were illegal, and those were the strikes that made Lutter tap.
