Welcome Mate bit of advic, be careful when starting nba...
I made the mistake and just buying a whole bunch of random set from different years, n random nice looking cards.
the best advice i got was to find an era or brand that attracts you for me i like really out there crazy styled cards the crazier the better, and if you wanna just do player specific look at 1 unknown rookie and a all star player who you will spend a bit more money on.... so mine were KD and Reggie jackson,
i wasted a good 200 bucks on cards that i thought i was into but just not as i rushed it.
