Karl Malone is one of the most underappreciated scorers in NBA history. Malone ended his career as the 2nd highest scorer of all time and has since only been surpassed by LeBron James. That is an incredible feat but is often forgotten because Malone played most of his career in Utah and never won a championship.
Regardless of his championship history, Malone is often considered one of the greatest power forwards in the history of the game. He and John Stockton were perennial contenders in the '90s but lost 2 championships in the Finals to Michael Jordan's Chicago Bulls.
Malone was a quiet and tough player throughout his career but has shown a lighthearted side in recent years. From being in commercials where his ringless career gets mocked to even participating in a video with Red Bull where he pranked Anthony Davis by being undercover during a shoot as a janitor.
Malone is dressed up in a janitor's overalls and is given a fake wig and beard to not arouse suspicion. Karl would be within eyeshot of everyone and was being hard to deal with, complaining about the shoot and asking AD and others to wrap it up so he could leave.
After Karl got onto the court and told Davis that he didn't want to go back to being the 'Mailman', he took off the wig and revealed himself. He and AD dapped it up with both players sharing their appreciation for each other after coming face-to-face.
This video made Malone show off more of his humor and charisma than what anyone got a chance to see during his 20-year career. Davis was very clearly fooled as he asked his security to get rid of Malone from the premises after he was interrupting their shoot way too much. This was a hilarious idea and should be used more often, with different legends surprising different stars of today's NBA.
