This is how i remember how good Heenan was putting over talent. I was watching MSG Classics a few years back and it was a face vs face match Koko B Ware vs Tito Santana and Heenan says
"You know what Monsoon I don't like either guy but what we're about to see is a great technical high flying match both of these guys can go in the ring"
This was at the height of his heel WWF run and he's putting over two faces he would usually dog week in week out but when you have 2 faces going against each other you have to put them over and do your shtick at the same time,that's the difference between Hennan and everyone else playing the heel commentator role.
