Somebody get this to Mike Brown...QUICK!
Start Anderson Varejao on Dwight Howard instead of Zydrunas Ilgauskas. No, Varejao isn't nearly strong enough to back down Howard - but neither is Z, so it's moot. Varejao IS quicker and can actually stay in front of Howard and force Howard to choose when to take his fouls in getting to the basket - unlike Z, who is too slow and spent most of game four watching Howard dribble right past or around him. Early on, before the team gets into the penalty, rotate Joe Smith onto him - he can also defend well for a big man, certainly well enough to throw some meaningless fouls at Howard - and then rotate Ben Wallace onto him and wear him out and get him into early foul trouble.
Speaking of Ilgauskas, get Delonte West off of Hedo Turkoglu. West is a great defender off of the dribble. Turkoglu doesn't dribble and can't create his own shot. What Turkoglu does do is post up and shoot jumpers, which he can do pretty well when he's shooting over top of Delonte West, who is about seven inches shorter than him - unlike if he were being defended by 7' Zydrunas Ilgauskas.
The Magic like to move the ball and always seem to squeeze in that one extra pass to find the open man on the perimeter. In game four, that meant 17 3-pointers! They do that by forcing the defenders to come inside to pick up dribblers coming off of screens and traps. Try rotating the guy off of Courtney Lee, who's averaging a bit over 7 points a game this series instead of Mickael Pietrus (who has single handedly outscored the Cavs bench in each game this series), Rashard Lewis (who's averaging almost 20 a game) or Rafer Alston (who's averaging almost 15 points a game). On a similar note, if a team has shown that they can shoot over 40% from downtown then you don't need to automatically doubleteam the ball everytime that they take it inside. LeBron James, Delonte West and Ben Wallace are all great on-the-ball defenders - let guys stay home on the outside to cut down on the wide open looks that Orlando's shooters have been getting all series long.
LeBron had two awful passes late in game four that were nowhere near anybody. The offense has looked similarly out-of-sync plenty of other times this series. If guys aren't on the same page, get them there - run a set play or two and force somebody other than LeBron to take some shots.
Have some sort of logic with your substitutions off the bench. Nobody seems to have any idea what guys will be coming off of the bench, when or what they'll be doing. Wally Szczerbiak and Sasha Pavlovic have alternated games and taken 15 shots between them through four games. What was gained from having Joe Smith play four minutes in game four without taking a shot? He didn't even come in and foul anybody!
The Magic are a heck of a team and, on paper, a tough matchup for the Cavaliers. While the Cavs are one lucky shot away from having been swept in this series, they're two three pointers from Rafer Alston away from being up 3-1. This team can win this matchup if they start approaching it intelligently.
