It is true that D'Antoni's system is heavily offense-oriented, but if Dwight Howard can man the middle as the defensive stalwart he's supposed to be, the Lakers will be a tough team to beat.
His system doesn't work with a oldish Lakers team. Run and gun offense isn't going to do it. Kobe and Nash aren't in their primes anymore. Gasol and Howard aren't meant for it either. This team is a half court oriented. If they can somehow, get the ball inside to Howard and Gasol, then they can space the floor for their shooters.
This is all speculation though. A coaching change, no matter how drastic, isn't going to improve a team's situation if the players are the root of the problem. Pau needs to step his game up, and their bench needs to be improved somehow, especially with Jamison doing little to contribute to the team's welfare.
I agree with this. Their bench, I think, has been slightly improved compared to last year's bench. There's a lot of improvement to be made but they're working their way towards it.
Memphis and New York have been unexpected surprises so far. Both blew out the Heat, the only two teams to give the Heat losses so far. The Grizzlies will have a chance to really prove themselves against the Thunder, while the Knicks are expecting the Spurs soon. They will be playing each other on the 16th, a match to look forward to.
Grizzlies so far are proving themselves against the Thunder. But still some time left right now. With Westbrook and Durant being athletic clutch players they can break away with a scoring run. Losing James Harden is big though. He made other players better. Kevin Martin is a different scorer then he is.
And finally...Spurs start off strong. Again. Seems like in recent years, the Spurs have crushed their competition in the regular season but have been unable to convert that dominance to playoff form. Their roster looks pretty solid this year though, and Tim Duncan is playing like it's ten years ago. The only worrying factor is the absence of a reliable superstar. Duncan will inevitably wear out at some point in the season, and I haven't been too keen on Tony Parker since he lost that mid-range jump shot.
Spurs should have won the Western conference finals last year. They had a commanding lead early but stumbled and lost it.
Other notable teams this year are the Bucks, Bobcats, Timberwolves, Hornets, Rockets, and Jazz. These are the 'improving teams' category.
