MyCareer NBA 2K15 - Sacramento Kings (Center #66)

Hello Guys,
Can I ask you all something about MyCareer in NBA 2K15 ??
I just play it a few days ago, and i confused about how to get the sponsored like nike, air jordan, or else ??
I played as a center in Kings, and i'm in starting line up, my progress is good 32,5 PPG, 13,4 RPG and 3,3 BPG, but nike or air jordan don't sponsored me, why ?

Anyone can you share your opinion :):):):)
