I agree with your conclusion, but it seems you are arguing against a point that the author did not make. The author does not say "that single play make Rondo better than Williams", he says "this play is a perfect example why."
I've seen Deron make plenty of hustle plays also, if that's what the author is trying to imply? There is no article really, when I opened it up I figured there'd be more than just a few words and a clip.
Another thing-his header is in regards to Rondo/Dwill. Does that mean he is merely comparing the two, or implying that they are the 2 best in the NBA at the position? Hard to tell but at least Deron garners enough respect that it doesn't say "Why Rondo is better than Chris Paul (or Parker, or Kidd, Nash, etc)"
