Away from the heat of the game:
I know there was back and forth last night, after Anunoby hit the game winner, about "why did the Celtics employ a zone?" with 0.5 seconds left. I'll admit I'm not a hardcore X's and O's guy, but I don't buy the logic of the zone there. The point was made that you can run lots of plays against a man to man to shake someone free. True. But it seems you can run lots of plays against a zone to free someone too (e.g., what if I stack five players at the foul line, disperse them, then restack maybe three on one side of the court?)
It seems last night, with half a second left, you should mostly fear two things: (1) A play leading to an easy tip in (2) Someone getting the ball, wide open from behind the three-point line, in a comfortable position (i.e., with his feet set).
With a man to man, it seems more likely a player would get the ball either in motion or having just ducked behind a screen (so coming off motion), and would probably have a hand in his face. But last night Anunoby was just standing there, unguarded. He was so incredibly wide open that Lowry could throw an overhead rainbow pass -- not a direct slingshot -- and a streaking Jaylen Brown (who is far from slow) could be so far away that he didn't even graze the shot when he leaped forward.
I know hindsight is always 20-20. But is it really acknowledged among strategists of the game that a zone is the best way to go with less than one second remaining? A zone just seems vulnerable to overloading and also to giving players too much space to comfortably catch the ball. Curious what others think.
