I'm torn on this, I really enjoyed KG's time with the Celtics and am impartial if his number should be retired.
I think the Celtics just have so many numbers retired from years past that should not be up there and that's why I feel they need to be more selective going forward.
Take Reggie Lewis for example, he is one of the few absolutes IMO that should be retired. Him, Russell, Bird, Heinsohn, Pierce are all no brainers for me.. but people were ready to take it down to get KD a few years ago. How many more time will we be at risk of similar scenarios for years to come? There are only so many desirable numbers to go around.
