I agreee, that the overloaded schedule wears player out. I agree, that slowing down the courts can do the same. But I disagree with his (the author of this article) and your kind of argumantation. You can't compare the present situation with that one in the past. Tennis has become more athletic and exhausting.
In the first place you have to consider, that tennis is overaged. 46% of all Top 50 players are 30+!
And this is the group, which dominates the Masters and Slams. If they get not enough time for regeneration and exercising BETWEEN important tournaments, the players will become exhausted and injury-prone. We will get many retirements, injuries and strange results (like now at Cincinnati). Even young Zverev lost his first match after winning a Master (lost at FO and Cincinnati Masters).
Secondly the number of played matches is irrelevant. Because of many reasons: Important are match durations and playimg style (For instance Cilic needs for a Slam match about 70 minutes, while players like Murray and Nishikori are playing often much more than 2 hours), court surface (clay court ist more exhausting due to long rallies, grass court is less exhausting) and you have to consider physical condition and genetic differences between the players.
Even Federer'scheduling is not so smart. It seems, that he needs about 2 or 3 months pause betweeen grouped tournaments. He tried to play Montreal, Cincinnati and the USO in a row after Wimbledon and got problems with a back injury even in his first Final (Montreal).
With the most other posters I agree.

Karloviv is the oldest player in the Top 200, but his best ranking was only #14.
Maybe his playing style is not sufficient to become a Top Star (Top 4, Top 1).
