Bit of a cherry pick. He was describing Jeff Green as he is, which is a washed up extremely inefficient version of what he used to be. Marcus Morris and Jeff Green aren't really similar, except similar scoring (not similar efficiency) and rebounding. Such things as motor, intangibles, BBIQ and consistency aren't shown at all by a per36 snapshot that isn't even relevant.
Some other stats that are close, %s, assist #, defensive stats, foul rate? And wasn't he describing his impressions while watching Jeff Green play for us? I actually wouldn't knock either guy's basketball IQ. But both are highly inconsistent for sure.
Either way, his first line:
Does nothing to get them past Golden State.
and his last:
Not to rag on the guy, but I just don't think he adds much. I will say that the price tag is a bargain in the current market though.
are spot on.
