You contain him with mismatches and a team defensive philosophy. For the smaller guys on defense, you have to front him, have the perimeter players pressure the ball to make it a difficult pass, and have defenders on the wing be there to help deflect passes if LA tries it. Also, have Wade and James constantly attacking the rim, trying to get him in foul trouble. On the other side of the ball, put Howard in PnR's with weak PnR defenders (Nash, for instance), and force him to guard guys like Bosh who will take him away from the rim, or make him think twice at least about contesting penetration. All easier said than done, especially with the players he has around him. IMO, on paper, LA is the better team. Their top pieces fit better and in some ways have greater versatility, and they have a solid supporting cast. However, Miami figured out in the playoffs that a small-ball lineup with James at the 4 can work because of how good and versatile he is defensively and offensively. Now with Ray Allen, they will be even better with that small ball lineup because they will have another dead-eye shooter who is somewhat versatile and can make smart basketball decisions (unlike, say, Cole, Jones, Battier, and injured Miller). Basically, the formula for beating this LA team is the much the same as it was last year because they still have a major hole defensively at PG, are relatively unathletic at 4 of the 5 positions in the starting lineup, and their core players aside from Howard are still getting up there in age. Kobe isn't a great spot-up shooter, Artest is still awful offensively, Pau will probably still wander the perimeter, and Howard has some limitations that could be magnified by his back issues. If you want to beat LA, you have to space them out and force Howard to make decisions on the defensive end once penetration is made, and on the other end of the floor you have to blitz them with aggressive defense and allow the athleticism on rotations to make up for missed opportunities.
