A poll would be nice here.
I say no. I love KG, but 6 seasons and a ring (while transforming the mentality of the franchise) doesn't warrant a jersey retirement. I know people will point me to other Celtic retired numbers who were less influential, but don't we also think KG belongs to Minnesota? I know he can be retired in both places, but it would just feel like we are stealing him from them, kinda.
Because, think about this. If we retire #5, then where do we draw the line? Does Allen get retired too? But then what about Rondo? His #9 is already being used by D-Jax.
I'm a proponent of retiring his name though. Like we did for LOSCY. Something like "KG" in the rafters would be pretty cool.
