Same reason you saw Tyrus Thomas listed at 6'9 or 6'10 then he measured at 6'7.5 or shorter at the combine. I don't really get it either because how tall you are without shoes doesn't matter. You play with them.
Simply put, people like to question a height so I wanted to make sure there was no questioning possible.
Because everyone plays in similar shoes and players will measure in shoes with extra padding to add to their height. Andre Drummond's shoes added like 2.5 inches at the combine. Do you really think he's going to play with those shoes on? Extra weight and high risk of ankle injuries.
Measuring without shoes takes away the opportunity to game the system. In my opinion, "standing reach without shoes" and wing span are the two most important measurements of length. A long neck is not going to help defend.
