Lillard took some 248 games to get to the feat as Chicago Bulls former NBA M.V.P. Derrick Rose took 240 games to get to those numbers. Now with no L-Train as a Scoring Option Lillard's P.P.G. should be headed north at least in 2K15-16.
Those other players to get to 5,000 points and 1,500 assists but not as fast as Dame or D-Rose...King James, Carmelo, @kdTREY5, Wade County, Kyrie, Blake Griffin, and former Rip City Star BRoy7 dba Brandon Roy.
