Spurs my devoted NBA team?

Hello,

Next season I want to start to be a full NBA fan and looking for a team to support for the rest of my life. I hate seeming as a bandwagon fan so I hate GSW and Cavs. I'm looking for a team with these characteristics and looking for input:

1. A star or superstar? What is Leonard considered?
2. A team that either has a great future with young ones or a decent team with a good team and good young players that will have a good future.
3. Spanish player would be nice as I am half Spanish. Gasol I hope returns.

Any input would be nice as really the only other teams I'm considering are the Wolves, Philly and Raptors. Trust me I'm already pretty leaning towards to Spurs but just want input as I'm worried about the future.

Thanks
