Rojo made the mistake of not checking ot see if there was already a thread on this. There was. So we merged the two threads and kept Rojo's title. The first title was "Steven Gardiner replaces Quincy Hall as a GST Racer"
The rigidness of these athletes is ridiculous. So a professional runner can’t run a 400 one day then a 200 the next? And get paid a ridiculous amount of money to do it? They cry about opportunities to make more money, then are given the opportunity then make some excuse because they might have to perform for the money they demand.
Diamond League is threatened by GST. Shanghai likely offered Qunicy Hall more money to compete in their meet. China is a large market for track and field with potential sponsorship opportunities (non-shoe companies). If I were in Quincy's position I would want to go to China to make new contacts.
Looking at the top stars who competed in Xiamen it is a good guess the Chinese are paying top dollar to the top performers.
