Grew up a Jazz fan due to them being the first team I won the title with in Lakers Vs Celtics and the NBA Playoffs on my first PC. Stockton had blond hair in that game so it wasn't until a year or so later when I began collecting cards, before they became so insanely popular, that I really knew what he looked like.
I've always been a fan of ball movement, playmaking, and the art of the assist so Stockton was my idol who I modelled my game after especially being an undersized PG.
Got to work with a few organisations in some capacity when living overseas namely Boston, San Antonio, and Portland so became team neutral for a few years.
When that stopped and I had lived in PDX, the 503, for several years right as Rip City was reborn with Roy and Aldridge I became a steadfast and loyal Blazers man. Having followed little known Oakland guard Damian Lillard since high school I really lucked out when the Blazers drafted him.
Why the NBA? The high level entertainment, the stars, the skills and the show. It's one of the few sporting leagues around the world that truly has it all. And though there are dynasties and several teams who are constantly mismanaged its not the same teams every year like it is in European football. We've had this generation's Leicester while the NBA has small market teams like the Spurs and Cleveland bob up with titles while others regularly compete and contend.
As far as players go these days its Dame, the Aussies, and to a second team in Brett Brown and his Philadelphia 76ers (would support them even without Ben as I've known Brett since shortly after he first arrived in Australia).
Other all time fave players include Magic, Muggsy, Pierce, Toine, Timmy D, Malone.
