Lebron was drafted in 2003. You have to go all the way to 2011 draft to find the next #1 pick (Kyrie) that is still playing in the NBA. Crazy
Players left from each draft class:
2003 - 1 (Lowry)
2004 - 0
2005 - 1 (Paul)
2006 - 1 (Lowry) + technically PJ Tucker, although he may never see the court again
2007 - 4 (including Durant)
2008 - 6 (down 4 from last year - Rose, Gallo, Hill, McGee... I could see McGee getting signed to a 10 day by OKC or something)
2009 - 5 + James Johnson who technically counts
2010 - 1 (George)
2011 - There is a bunch left, but they have an unbelievable amount of old guys that are on contracts but provide zero production (the ****tier Morris twin, Reggie Jackson, Cory Joseph, Alec Burks, soon Isaiah Thomas and Bismack Biyombo will get 10 day contracts) PLUS Davis Bertans is still getting paid this year although he isn't in the NBA and Bojan Bogdanovic's corpse is still on Nets roster waiting to get Frankenstein'ed back together. Still some legit NBA players too - Irving, Klay, Butler, Vucevic, Tobias Harris, JV, Kawhi if he decides to play.
