The possible explanation for players leaving Nike...
Why is Nike not interested in signing the number #1 player in the world. Djokovic has become like Federer in making it to the semi finals in all the majors and pretty much most other tournaments as well. Djokovic needs a bigger sponsor and with question marks about Nadal and Federer getting older why not lock up the Joker now? Tennis will continue to grow in this country and it's much cheaper to play compared to golf. Green fees in this country are ridiculous.
