Fascinating article. I wonder how the next decade will compare to when the Big 4 played. Tennis is now doing a three year trial of guaranteed baseline earnings but only for the top 250 (https://www.atptour.com/en/news/baseline-december-2024).

Tennis players portion of total revenue is the lowest among major sports- 17.5% (https://tennishead.net/tennis-players-receive-smallest-reven...)

I wish there was more funding and support for players below the top 250 and not just in countries with strong central tennis academies.
