What is the tie between Julius Erving and the Spurs?
The link comes from a blog, not from Julius Erving himself. The site 20 Second Timeout wrote on May 29, 2013 that "the San Antonio Spurs are his favorite team other than the Philadelphia 76ers." That is one outlet's claim, and nothing here has Erving saying it in his own words, so it stands as a reported background tie, not a stated fandom.
Does it line up with where he came from or played?
Not with the Spurs. Erving was born in East Meadow, New York, and raised from the age of 13 in Roosevelt, New York. His career ran from 1971 to 1987 with the Virginia Squires, the New York Nets and the Philadelphia 76ers, the last of which he played for from 1976 to 1987. The blog's own wording names the 76ers as the team ahead of the Spurs, which fits the long stretch he spent in Philadelphia.
