Because Nike’s recent shoes and clothes are more advocating power and speed than Adidas, and among the new generation of NBA players, only LBJ can be equipped with both power and speed, so Nike will use LBJ Signed as a superstar player.

Careful friends can take a look at the plastic models in Nike's recent stores. They are much stronger than those in Adidas. This is also related to Nike's change in sports philosophy.

Nike advocates individual ability, and its stars such as Kobe Bryant and football's Cristiano Ronaldo are all known for their outstanding personal abilities. So Nike has reason to sign players like LBJ.
