Watching the Celtics vs Raptors game it struck me that I'm simply not scared of the Raptors when the C's play them. Its not that they're bad, it's just that they don't do anything that bothers the Celtics strategically and their best players don't really pressure the Celtics. It feels like a game the Celtics will control. The Celtics may not always win, but if they play well they SHOULD.
So that brings me to my question, leaving out the elite Western Conference teams (OKC, DEN, HOU) who are scary just because they are very good, what teams worry you when the C's play them? Either because of their strengths, particular players, play style ect?
One example for me: The Cavaliers. I know the Celtics have beaten them 2x already, but every game feels stressful just because you know Mitchell can go off at any moment. He's always been a player the C's struggle with.
