How can I choose Lebron in blacktop??

I would like play with players like Lebron, wade etc in blacktop but the aren´t there to be choosen.
Some people said that I need VC (Virtual Coins) to unlock those players but I can´t find those VC and I can´t find the option to unlock them
NOTE: I can play Online because I don´t have internet.
I Sorry about My ENGLISH.

There is a blacktop roster you can use in the downloads section

Or with the roster editor you can change his ASA id to 0
