Celtics exposed how to beat the Lakers in a seven game series last year and because of it San Antonio will probably take the Lakers out of the playoffs this year.
You have to rough up the guys underneath, expose the Euros for the horrible defenders that they are, and front and deny Kobe at all times. San Antonio has all the tools to do just that Bynum or no Bynum. If Yao Ming played like a physical beast Houston could do it too.
The key is exposing and going at Radmonovic and Vujacic. They give up easy baskets and foul after a while. They then have to sit and then LA has no one to space the floor because they haven't got any more dependable outside shooters but Kobe. So you can pack it down underneath, beat up the low post guys which absolutely gets into their heads(see Gasol and Odom in the Finals. Posey and Powe had Odom constantly trying to pick a fight and his head was not in the games.), deny Kobe the drive and force him to beat you outside by himself.
But if you have players that can deny and shadow Kobe(Pierce, Posey, Bowen, Artest) then LA is done. I'm an amateur and I saw this. What do you think Popovich, Adelman and Scott saw and what do you think they are going to do with that knowledge in a seven game series? The Lakers exposed that they can be physically handled. Play great defense and throw in a little old school Pistons Bad Boys attitude and the Lakers will fold.
