You are full of ****. I follow the NBA and the draft like a mofo. Marble, Kane and Ejim were all lauded as hard workers with versatile games. Kane and Ejim are a bit more skilled but undersized. Age killed Kane for sure. Between ESPN, Yahoo, NBADRAFTNET, and NBA.com, I haven't seen one article or heard once on TV that Marble (or Kane/Ejim for that matter) had a bad work ethic. Quite the opposite, actually. Marble and Ejim both steadily improved throughout their careers. Zero chance that happens if they aren't hard workers.
I am pretty constipated today...
