@phightinphils: “Happy Birthday Doc! You are what made me an NBA fan and got me to my first Championship parade in Philly back when I was still in elementary school. For me, your era will always be the best the NBA had to offer. Sixers, Celtics, Lakers?! Forget about it! Have a wonderful day!”

@AnthonyGaenzle: “Proud of my son. He chose #6 because of Julius Erving for his jersey this year. He’s 9, so he obviously never saw him play live. But he’s seen replays and respects the game.”

Erving had averages of 22.0 points, 6.7 rebounds, 3.9 assists, 1.8 steals and 1.5 blocks per contest while shooting 50.7% from the field in 836 games for the 76ers.
