I think he was decent.
I mean he wasn't necessarily worse than others.
He was an experienced fighter and not just a theorist. Sometimes he briefly talks about his own experiences and gives interesting additional information about the old fighters. And he was a legend, iconic and a polite host. Last but not least, the old fights were great.

But actually, I never paid much attention to the commentators. First of all, I don't even know most of the English-speaking commentators because it's not my mother tongue. Secondly, they usually say what is happening at the moment. Of course, I can see that myself. So, for me it's more of a blah blah in the background.
