Look y'all, Marvin was the consensus number two pick of the draft this year. Any team picking number two would have picked Marvin, not just the Hawks. I honestly think it's popular to bash the Marvin pick at the moment simply because the Hawks chose him.
The Hawks are an easy punchline right now because of our low attendance, our 13 wins, the Belkin fiasco, and our alleged over-abundance of swing men. If the Hornets had taken Williams you'd be hearing all kinds of priase for the pick and how they took a potential superstar that fit a need well.
There are good reasons why we added both JJ and Marvin this summer. As for JJ, I think BK wanted a big, long, versatile PG (unlike Chris Paul); and he wanted a G who could shoot (unlike Deron Williams). JJ fits into both those categories better than either Paul or Deron.
As for Marvin, we needed more shooting, and Marvin gives us that. While it's true that Harrington, Smith, Marvin, JJ, and Childress can all play Small Forward, the pieces we've assembled are not duplicative. Harrington will be gone by the trade deadline; JJ can play the one, two, or three; Childress can play the two or the three; and Smith or Marvin can play either the three or the four.
So those pieces fit together well and give us an extremely long, extremely athletic, extremely versatile, and now a very well rounded balance of shooters and slashers at the 1-4 spots. Two years from now this could be a very, very good team.
