KG wore #21 all his years with the Timberwolves, as Malik was his favorite player when he was younger. This is why Malik had to wear #2 with the Wolves when he was with them. They were incredibly close friends. Remember, Malik was killed on his way home from a birthday party for KG. A few years back, ABC had a piece on a pregame show to a playoff game that was the 10th anniversary of the death about KG's continued link to Malik. He broke down during the interview.
(you can find it on Youtube:)--really worth the 4 minutes to watch it.
KG may have been the one who kept Malik's locker empty while he was still in MN, I don't remember. That KG is doing this #2 thing for Malik is no surprise at all. I miss "Sleek" Malik.
