Various linups are in the game at various stages, the above lineup has been and can be again an efficient scoring unit. Three "guards" that can pass along with two scoring threats in Horry and Duncan in the post.
Horry is also more agile than Nesterovic allowing him to match up better with the suns who are playing small ball currently.
Barry can be subsituted for Bowen if you want more of a defensive focus.
This lineup still leaves the chemistry that Malik Beno and Brown have to come of the bench providing a spark when the starters sit, Nesterovic also gets a chance to be more detromental against the suns second team, which features "real" centres as opposed to athletic freaks.
However D'Antoni has not really been playing his fives much, consequently Rasho is not going to have an ideal matchup.
I dunno about you guys but I doubt that Rasho would be "aggresive" and "demonstartive" enough to over power weaker opposition and will most likely end up having circles run around him by Amare the opposing C.
A lineup change can work for the better as I feel it would in this instance, by all means we need to try and force our game upon them but its unlikely with Nash at the point, he is very good at creating/maintaining a high speed fast break game.
