That's right. Especially LA Lakers whose line-up is focused on inside games with LeBron dictating their tempo. Based on their game on pre-season against GSW, the Lakers seems to be unstoppable inside the paint and that's a big problem for most of their opponents.
I have watched the highlights of the Lakers vs GSW game and the Lakers simply dominated the shaded area with Lebron, Davis and McGee. To be honest they have good inside players and a good backcourts too. If there will be no injuries for them throughout the whole season, there is a big chance that they will reach the playoffs this season but still don't expect too much for them even their roster is better now compare to the their roster last season.
Im confident that the Lakers will secure a top seed to enter the playoffs. With AD in addition to the roster alone is already a huge move for the Lakers management. When they signed AD thats an automatic playoff-bound for the Lakers.
I have watched the game too, and offensively I can say the Lakers easily dominated the game from every area in the field, and youre right, most of these areas are were AD, Lebron, and McGee positioned themselves.
Im afraid the GSW will miss the playoffs this year if Thompson remains unhealthy for the rest of the season.
Here some playoff prediction from Chris Webber :

Chris knew the GSW lost too much intensity without KD and Klay.
Now, the NBA fans have just realized how underrated Klay was. Steph and Green wont make it alone. I know DLo is in their current roster, but I doubt he wont make enough impact this year with GSW this year.
