C'mon dude, if I talked shit about the Heat playing any team 8 times and winning 6 of them, you'd call me retarded. Why is it so fucking difficult for you to understand that some teams matchup well with others? The Pacers can't beat a lot of teams, but they the Bulls (a division rival) very well. Obviously you can't get a grasp on what a rivalry is.
I don't live in Midwest area, so I don't know the intensity of this "rivalry". I haven't really heard much about this "rivalry" from the media, so I'll take your word on it.
All I know is that the Pacers have risen their level of play, and the Bulls are playing down to their competition.
