Believe it or not, I think one of the biggest keys to beating the Suns is keeping Hill and Richardson off the glass, and outfighting them for some of the long rebounds off of 3-point attempts. Those two guys pick up A LOT of the rebounds that get the Suns easy points, and they just killed Portland.
Nash and Stoudamire are going to get their points. A lot of the Suns losses have involved Richardson having a sub-par game. He was unconscious against Portland, but he normally doesn't shoot FT's all that well. Pushing him hard on defense is key, even if it means burning a few fouls - just to try and keep him out of rhythm.
I know Pop won't do it, but I'd love to see him put Garret Temple on Dudley when the Suns put him in the game. Dudley's points have helped the Suns a lot over the course of the season. I think Temple would kick his ass defensively. And the Suns would probably ignore him out on the corner - at least until he knocked down a few 3's. Temple has the length and quickness to run Dudley off the 3P line, where he does the most damage, and that is tiring work. That's one of the ways Pop could create some of the depth that TimVP talked about.
