Man this is tough - I would love to take someone like Elvin Hayes or Ewing or Bill Walton, the career stats are great but I just really like someone like Anthony Davis' career prospects if he stays healthy, I have more frame of reference and he's hugely exciting to watch. Is he PF/C or PF?
Even like Nate Thurmond, some of his career played when blocks weren't recorded hurts what would be useful in the final simulation when the teams are complete.
