Ugh, how does this really upgrade there D, they are going from worst in the league in terms of PPG. Raja for JJ is a wash and Thomas is slightly better than Q, with that you only have 2 better than average defenders for their position in Marion if he's playing the 3 and Raja at the 2. With that being said, you can't change a team and expect the same results. These are significant changes. Defensive presence and the suns shouldn't be in the same sentence. There's a huge difference between defensive teams such as the Spurs and the Pistons, who both have 2 of the best interior defenders on top of having one of the top 3 perimeter defenders (Bowen and Prince) on top of having others who are effective defenders (Manu, Hamilton, Billups, Nazr). It's a team mentality on these teams. You honestly think bringing in Thomas and Raja is going to switch the Suns from Offensive Machine to defensive team, you and I know that isn't true. The reason the suns were so effective against every other team than the Spurs is that they ran the ball so well. They did run into a wall, it's called the best team in the league.
All I'm saying is I don't think there going in the right direction. These moves are at best lateral. An up move would have been to bring in a guy like Ben Wallace, or Tyson Chandler to clog up the middle, what they did was piece together some moves.
And to your quote in which you say "you do realize they didn't win." I do realize that, but do you realize they went from a horrible team the year before to WCF with effectively adding 2 players in Nash and Q from the year before. They couldn't beat the Spurs with JJ being 100% effective and now they switch gears. I can understand them getting rid of Q, I've thought from the beginning he was a bum. I can understand why they have to let JJ go, but I don't think the team will be nearly as good because of this. The team won a lot of games for 1 reason and 1 reason alone, they could put up a tremendous amount of points. 2 of the players who remain in the starting lineup and last year were considered MVP candidates, are still there and still don't play very good D. They aren't changing their mentality this year, I don't understand why you would think changing parts for effectively weaker parts is going to add up to more effectiveness in the playoffs. WCF ain't shabby especially for a team that didn't make the playoffs the year before.
You act like D'Antoni who effectively didn't coach that much last year is going to change directions. As long as you have Nash at the helm, a team isn't going to be very defensive. He's terrible defensively and things stem from there. D'Antoni seemed to not to know how to coach D last year, do you think it'll change. Coaches don't change philosophies, I doubt D'Antoni is going to suddenly dawn upon playing D in the next couple of monthes although we all know you need D to win the title, well atleast every team that's won since what 1988 has played pretty good D.
