That's absurd, IMO. No disrespect to the legacy of George Mikan, but that's ridiculous: how do you justify naming the MIP award after a guy who averaged 28ppg in his first official NBA season, and never actually did better than that? He was the first marquee player ever in the league but, improved? When? Not after the BAA/NBL merger, that's for sure.
They should absolutely name it after Antetokounmpo. If they don't want to wait until he retires, name it after the only recipient currently in the Hall of Fame: Tracy McGrady.
