"Jeff Van Gundy was a proponent of trapping the ball-handler on pick-and-rolls. Adelman will never trap with his centers, having Yao Ming or Dikembe Mutombo instead sinking back into the lane. He also will more often have guards try to guide the ball-handler toward the baseline."

"Van Gundy insisted on contesting every jump shot, and last season wanted closeouts, even if they meant going for pump fakes, believing that shooting percentages decrease off one- and two-dribble jump shots when compared to spotting up. Adelman will more often let a specific game plan determine whom the Rockets must close out."
As a rule, it's safest to treat each situation as a unique set of variables that require a unique solution. If you try to apply a science to everything in the world, the science is bound to fail. One of the strong points of the Rick Adelman system is its flexibility. Most often that flexibility is associated with the fluid offense, but also has to apply more broadly to an entire philosophy of basketball. Van Gundy's philosophy of rigid, hard and fast protocols for playing both ends of the floor are unmanageable and in the end make for a very long and grueling season. Essentially, the Van Gundy system is an 82 game playoff style of basketball that most players have a hard time playing for 10-20 games at the end of the year. Adelman's system is much better suited to keeping players interested and will prove valuable in the specific instances of Tracy McGrady and Yao Ming. A lot will be asked of these players and it should be interesting to see how much lighter they appear after the All Star break. Two statements that Coach Adelman made tell a big part of the story, in my opinion:
"I want to do some of the things they did because they were so solid at it," Adelman said. "I've said before, Jeff did a great job with them. When you start with the guys we have like Rafer (Alston) and Shane (Battier) and Chuck (Hayes), there's good defenders out there. You're going to be pretty solid defensively." "A little is on veteran guys, to see if we have the knowledge as the games go along, to see what the offense is trying to do," Alston said. "As opposed to having 20 to 30 set ways to guard, we might switch (on screens), or force a guy down, or chase a guy around screens. But it helps to have guys like Shane Battier and Chuck Hayes to facilitate defense."
What Adelman's system does that Van Gundy's didn't allow for is a level of trust among players that allows each man to do something different. On most successful teams the roles are divided according to strengths and weaknesses. With the dilution of talent in a 30 team league, there aren't enough big time players to fill out every roster. No one is going to have a team of 12 outstanding defenders, who can also play great on the offensive end of the floor. Guys like McGrady and Yao are more important as scorers than they are as defenders, and therefore should be complemented by the defensive role players on the team. Where JVG applied 48 minutes of tough pressure by contesting every shot, help defense from the Battiers and Alstons and others will allow McGrady to shoot the gaps, release early, and go for the steal. Yao will be able to hang back to block a shot or two, and cover for any mistakes that the guards make in man defense. Every player doesn't have to play tight defense on every possession.

I think you'll see a much better season from the Rockets than you witnessed in the JVG era. Houston fans should breathe a sigh of relief that a more open brand of basketball will be played on their home court that doesn't sacrifice quality for giving up some of the control from the coach's chair.
