So Tony Parker went to Peak...
Thus, smart Nike, smart Tony Parker but stupid Peak. This is a win, win, lose
If TP doesn't have a long-term deal with Peak, it's almost for sure he'll resort back to Nike when his contract is done. This is what happened to JKIDD, and what happened afterwards? Nike came out to release the "Career Pack", comprised of Zoom Flight 95 in SoCal, Mavs, Nets, and Suns colorways.
It doesn't hurt Nike that some of their aging athletes turn to other brands for more money, in the end, Nike knows they'll come back to them. Nike is almost default for basketball shoes- when athletes return to them, it only shows their shoes are superior and that athletes left them for the money elsewhere.
