The issue of calling timeouts when the other team starts making a run is something they need to look at, but IMHO the real problem is the Suns tendency to keep shooting low percentage shots when the other team is making a push.
The Suns don't really take horrible shots when teams are making a push, they just aren't making the shots they normally take. They still rely too much on long jump shots. They could get away with that in 05-06 because they had no reliable inside presence to get them easy shots. They had Amare back last year, yet they neglected to run much through him when teams were making a run. He is a guy who can stop runs by getting easy baskets, or getting fouled. That's an adjustment that the coaching staff needs to make.
In practical terms, the Suns style is not about D'Antoni, it's the Colangelos. They believe in the up tempo style and hired D'Antoni to make it work. They filled up on the kind players suited to that style well before Mike took over. JC went so far as to push through changes in the rules to encourage the kind of style he believes in.
Playing the style they play is great. I believe this is more how basketball should be played myself, only with better defense. It should be a fast paced game with ball movement, and great spacing. I don't see where they filled up on players before Mike got here though. They had Amare and Marion, and that's about it. JJ wasn't as productive yet, and LB was a rook I believe. When they got Nash, then things started falling into place. They then signed Q and began the small ball era here. The Suns are at their best when they play uptempo, but I don't think you can beat the best teams in the league if you can't adjust at certain points in a game. The Suns completely lack the ability to adjust, and part of that goes back to the Mike's philosiphy of speed will beat anything, which isn't true. But he won't budge from that, and presents no other alternative. If you look at a team like the Spurs, they can play up-tempo, and they can play slow. They are able to adjust and keep control of a game. The Suns can't.
I for one wanted more balance. I was amazed at how many people opposed the trade for KT a couple of years ago and how many people wanted to trade him last year and even right before the trade deadline. Where are all the "trade KT" fans now after it turns out he was essential to have a chance against the Spurs?
Beyond the need to play KT against the Spurs from the start, most of the other criticisms of D'Antoni seem to miss the core problem. The Spurs are vastly better at playing their style than anybody else is. If the Suns play like the Spurs, they lose in 4. Forget about how many All Stars the Suns have. Play slow down, bump and grind and the Suns lose.
One thing this team has always needed is size, so I'm not sure why some were opposed to the Kurt trade. I was sad to see Q go, because I became so attached to that team, but I understood why when we got exposed in the WCF's against SA, and I've always thought he should be a bigger part of the gameplan against any team. He doesn't hurt our running game that much. In fact, he helps it because he forces tough shots, and misses, which keeps the game moving. It seems silly to me to think that he should only play to be ready for the Spurs, but teams in the past have done things to prepare for one team in particular. How many teams stockpiled on bigs the past few years just to prepare for a possible matchup with a team that has Shaq? We aren't going to be able to beat SA at their game, and I don't why anyone would think we would, but you have to be able to adjust a little so you don't rely soley on 1 style of play.
D'Antoni's theory is that the only way to beat the Spurs is to get the tempo up and not let the Spurs get set in their half court defense. You may not like that strategy, but that is the approach the team has been built on for the last four to five years.
Yes, in order for this team to beat the Spurs, they are going to have to keep the game moving, but they should also be able play differently in stretches where the game isn't moving. D'Antoni refuses to address this. The Suns play their style of game better than anyone else, but somehow the Spurs are still able to run with us and beat us games where we control the tempo. What does that tell you? They adjust, and that makes them more dangerous. It's not just the Tim Duncan factor.
There is no evidence that changing the style during the regular season is going to make a material difference in being able to deal with the Spurs. D'Antoni's goal is to find ways to do a better job of what the Suns do best rather than doing a bad job of playing like the Spurs. Of course if they hired a hug to injure Duncan, I guess they COULD play like the Spurs.
I don't want the Suns to abandon their uptempo style, and I'm guessing that most others don't to, but it wouldn't hurt to throw a couple wrinkles in the offense. I'm tired of seeing this team be a one trick pony. Great teams make adjustments. Great coaches make adjustments. D'Antoni is a very good coach, but until he he becomes great at adjusting to teams, he won't be bumped up to that next level.
