Nah nothing weird about it. People chose different approaches to their definition of top sportspeople. Some went for greatest of all time and that. Fair enough if you want to type out Ali, Bradman etc. etc. it’s a free country. Personally I picked a list of sportspeople whose careers I’ve engaged with during my life and since I’m English a lot of them are English (None of my top three were mind).
And anyone suggesting people pick Kenny based on just winning medals for Great Britain have clearly never really watched her compete or heard her talk.
