Who is the tallest person ever to have played in the NBA?
According to the NBA, Manute Bol and Gheorghe Muresan share that distinction, with both standing 7'7" tall. Manute Bol played in the NBA from 1983 to 1995 with the San Diego Clippers, Washington Bullets, and the Golden State Warriors. Muresan played 1993–2000 with the Washington Bullets and New Jersey Nets, and starred in the 1998 movie My Giant with Billy Crystal.
Some reports claim that Muresan is a few millimeters taller than Bol, and Guinness World Records lists only Muresan as the tallest NBA player.
