His skill isn't the issue.
It's his gas tank and his ability to take damage.
The Wanderlei fight didn't prove anything imo, other than the fact that Silva can still KO anyone stupid enough to stand in front of him.
The Scott Smith fight, however, showed that Le doesn't have the chin or the conditioning to survive against heavy hitters, even exhausted, half dead heavy hitters with literally one tool in their toolbox.
But what really bothered me about that fight was the Le was given the rematch. That was a pure case of `oh, the wrong guy won, do over!'
Where as it should have been, 'let's build Scott Smith up based on his nasty come from behind upset KO of Cung Le'.
Instead, they gave Le a do-over and Smith lost all the well-earned momentum he had just gained from the biggest win of his career.
Scott Smith is a can with horseshoes surgically implanted into his hands. There is nothing to build up the wrong guy won the first fight because the better fighter had a year and a half layoff.
