Gillian Clark has commentated for like two decades? She’s won some golds in the less important ones, but she does have a few bronze medals in the big tourneys like the WC and the all Englands. Still definitely a very strong and probably the category of just under the top at her prime.

Morten Frost I believe is a newer addition to the commentary team. He’s won the world champs once (I think? don’t quote me on this), been in the top three for a long period of time. He’s definitely the more famous one.

Both are excellent commentators.

For clarity – Gill Clark was a top class womens doubles and mixed doubles player. She has done extremely well in commonwealth games (at least a silver if I recall…) and has been in the finals of the all england. I am sure she had many other wins as well, but those are the main ones I am aware of.

Morten frost has 2 world championship silver medals (no gold – beaten in both by chinese players) but has won many all england titles (5+ ? many consecutive finals) and won more than 50 other titles (most of them were grand prix – which were the equivalent of superseries). To be clear – 20 years ago and before, the All England was almost as prestigious as the world championships – so getting to the finals of that or winning it was a very big deal in the world of badminton.

I particularly enjoy listening to Morten Frost on his commentary of the top mens singles players. He has an excellent understanding of their strengths and limitations, and I think many players would benefit from his views.
