wow. you wrote an essay.
the main word is defense. those top 4 teams play good defense along with good offense, just look at their team stats. derozen will be fine in play.offs, toronto will be elite. also miami, wade is gonna play good play.offs and also bosh. any team in the east will have a tough series with them.
the cavs on the other hand, have so many weaknesses and holes which will be very easy to exploit in the 7 series play.offs, especially when teams can focus on one team at a time.
