Disclaimer: 17 minutes into the first episode here.
As a huge tennis fan, I question the choice of player in the first episode: Kyrgios. At the moment he is the most controversial - you might say one you love to hate - and if, like in Formula 1, you want to attract new fans to the sport, you will turn them off instead. What's worse, viewers might think all tennis players are like Kyrgios. They are not. Most behave like human beings who are able to accept losing and are respectful of opponents, officials and the rules. They generally exhibit basic human decency. Kyrgios is the exception.
I may update this review after watching more episodes.
