Exactly. The best way to shut Gasol down is by using "bully" tactics, getting physical, lots of energy, and flopping. Gasol would be given by Rodman.
Something that also isn't taken into account is Rodman's ridiculous rebounding ability. He gave the Bulls around 5-6 extra possesions a game, and created all kinds of and frustration doing so. The Bulls had such a great mental edge by their incredible rebounding and ability to create turnovers, which gave them a bunch of extra possessions which is something that will really wear on an opponent mentally.
While the Bulls did have their weaknesses (lacked a dominant interior player, and didn't have a whole lot of pure talent outside of MJ and Pippen), they had so many other advantages that more than made up for it. They had such great execution on both sides, crisp passing, great team balance and floor spacing, lots of versatility, and very high IQ players. The teamwork on both ends were amazing. There is no question they aren't as talented as some other teams, but they played basketball the right way, and did it better than any team ever has (in terms of execution, they were as close to perfect as it gets), which is why they are the best TEAM ever.
