The Spurs were fined 250k after sitting their guys against Miami in 2012 and Stern called it a disservice to the league. Granted, I think the fine originated from them not even being on the trip, but really what's the difference.
It would be easy, but since it'd be cropped to the wordmark on the badge anyway I figured I'd take it from an actual retro logo they had.
Yours is not a real logo and the wordmark on it is identical with their current one.
