The "team defense" concept of GS is "let's get so far ahead from our shooting 3s, that we force other teams to change their gameplan".
That was my comment regarding their defense unless I am mistaken?
Does this say GS is a bad defense? no.
Does it say GS is a good defense? no.
It says, that their team concept of defense, is more revolved around the "pace of play" and "playing with the lead". I believe that the tape of their play supports this.
