Kenny Bayless nowadays.

Mills Lane back in the 80s and 90s.

I liked Ron Lipton in the 90s before he got blackballed. He didn't want to play old boy politics with them dirty old boys of boxing...

Mitch Halpern was good in the 90s too. He committed suicide.

Very, very few competent refs in Boxing.
Far, far easier to copile lists of incompetent refs, no troubles compiling that list, those characters are broadcasted every week...
