The heat also retired number 23 for Micheal Jordan (who never played for them) so they probably aren't the best example.
I love KG, and he won us that championship, but I just don't think he was here long enough. If it weren't for the Nets trade I'd agree that his number will be retired, but I just don't think 5 years is long enough. He'll get his number retired in Minnesotta, and Pierce will get retired here, but that's it
