There needs to be more of a balance between fast and slow surfaces on the tour. Deep down every tennis fan knows Federer is correct whether they like him or loathe him.
It's like peope knew Nadal was correct when he was saying that there is far too much hard court tennis on the calendar.
If I had my way, every indoor tournament on the calendar would be held on carpet instead of hard courts. There are already so many tournaments held on outdoor hard, why do there need to be so many indoor hard tournaments as well?
There are just way too many slow hard court tournaments on the ATP calendar, and slow hard courts are the most dangerous and damaging surface to/on players' bodies as well.
