If KG plays out the 3 years with Boston I would retire his number and forever remember him as a Celtic. He's done so much for us, changing the culture, buying into the Celtic way, embracing it, and most importantly he's won.
I think Ray's is up in the air. If he doesn't win a title in Miami I could see him kinda being remembered as a Celtic. If he wins in Miami I think he will be remembered as a ring chaser.
