I always find it funny when people say "We need to play better D-fense" or "We need to rebound better". Living in Dallas, I hear that a lot about the Mavs fanboys too. The funny things is that there is kind of a yin-yang to all of this. If you change your focus to being a defensive team, then the offensive pace and flow are often impacted. The Mavs have (somewhat) improved their defense this year (mostly through personnel changes), but at the cost of not being quite the offensive juggernaut of years past. Are they better overall? Not really sure...I think they are about the same. If you throw a bunch of rebounders out there to improve your rebounding advantage, then your shooting and assist numbers will most likely go down as those players will probably not be as skilled in the other areas. So saying things like "If only we could.." is kind of like asking for Adelman to magically grant Peja the ability to rebound for example.
To some extent, you are what you are as a team. So you must play to your strengths and try to improve in the other areas where you can, but mostly you end up trying to hide your deficiencies. I don't think Popovich, for example, could implement his style of basketball here becuase we don't have those kinds of players. Can you honestly tell me you think the players on this team are capable of holding teams under 95 ppg (barring a shot-clock draining stall offense a-la the Fratello era in Cleveland). Which reminds me, there needs to be some sort of stat that shows the number of points per game allowed divided by the number of possesions that the opposing teams average per game..points per possession...that seems like a better measure of a team's defensive prowess.
Anyways, back to the topic of the thread...that's what coaching is all about, adjusting your style to the weapons in your arsenal. And if you have a problem with the style of basketball that the Kings are cooking, you should probably take your complaints (at least in part) to the man buying the groceries...and it ain't Adelman. Now if the Kings were averaging 92 ppg, or if he was coaching the Pistons roster and they were surrendering 100+ ppg, that would be a different story. He is doing well with the tools he has.
