Don't see how they can be considered "scary" good. Beating bad teams by wide margins means little to me.
They are no doubt good, and will only get better as they learn their own weaknesses and strengths as a team. That being said, I have yet to see anyone, including LeBron, show anything resembling that certain "it" quality other than Wade. I realize "it" is a completely subjective intangible that can not easily be defined, but, as a ceratin Sumprem Court Justice once said when asked to define "distasteful nude photography"; "I know it when I see it". This said "it " quality, is what seperates champions from 60 win 2nd round flame outs (cough...cough, LeBron I'm looking at you).
