This is NBA's fault as much as 2K.
There is no standardized measurement for players and their not remeasured. KD has his height listed 6'9" which is laughable, PG13 didn't have his height updated for a while and the shoe measurements are kind of ridiculous sometimes.
The in-shoe measurements are usually the player's height without shoes plus 1" to 1.5" inches then round up. So for instance, Love leaves his claim that he's 6'10" despite only being 6’'7 3/4" without shoes. One I never understood is Michael Beasley was measured at 6'7" without shoes 6'8 1/4" with shoes and is listed 6'10". (all measurements from DraftExpress)
The in-shoe and without-shoe measurements confuse people a lot. You see a lot of people saying, "{Insert player} is only 6 foot 7!" However, without the with/without shoes context it's kind of meaningless. A 6'7" without shoes is normally 6'9" by how with-shoes works.
To make it more confusing, players that come from EuroLeague tend to just keep the measurements from Europe that were without shoes. Thus often times the EuroLeague players in the NBA have the opposite problem of American players.
When you go There are a lot of players whose heights don't seem right and sometimes I find it difficult to sort fact from fiction. For example many believe Embiid is 7'2", he's announced at 76er games as 7'2", but NBA lists him as 7'.
Embiid was supposedly measured as 7'2" by the 76ers (via Fox Sports). Some say the measurement was taken in sandals, maybe he could be taller!? But wait... The 76ers have a monetary interest in saying he's 7'2". You can almost hear the 76ers selling it, "OMG!? Did you hear Embiid is a 7'2" beast! Buy your tickets at

It's all pretty silly. Yea, obviously 2K is in a unique position of having more access and resources than us, so it seems like they should be able to find a way to resolve this issue. That being said, the NBA's lack of standard measurements are as much the problem as 2K.
