Live 16 Rising Star

Ive been curious an tho ive searched the net for the answers with no luck, when it comes to RS, what are the features aside from playing 25 yrs, creating a unstoppable force?

Can the player negotiate contract or is it "auto assigned" like 2k did few years back when your player signed w any team they wanted at end of each year.

In live 15 you get options for different teams, but the contracts are not negotiable
