Actually Lawler's TDD is only 69% in UFC fights. That's at the low end of the spectrum for the WW class.
Realistically, the last top wrestler he beat in the UFC was Koscheck who was past his prime, going 2-2 into that fight.
He also did well against Ellenberger (who went into that fight coming off a loss). However Ellenberger went on to go 2-7 in his next 9, again clearly past his best days.
The two best prime wrestlers that Lawler has fought in his second run in the UFC is Woodley (who is coached by Askren) and Hendricks, both of which he lost to.
He has looked good stuffing shots against guys like Brown and Rory, but frankly they are nowhere near top wrestlers.
