I'm not going to lie, I have done random associations like this in the past. Trading everything for young talent to build into a powerhouse can be fun, though not realistic. It is the best part about a video game, you do what you want.
But to answer your question, I like doing it without a fantasy draft because I like playing the real teams, not fantasy ones. If I ran with this Nugget squad like OP, I would want to face the Super Friends in Miami, not Joe Johnson teamed up with Trevor Ariza and Andrew Bogut.
