One thing do boggles my mind on that last few minutes about that foul that had given 3 shots for Walker. Is that considered a shot attempt?

You mean this?
https://www.youtube.com/watch?v=urzFy765HO8I able to notice it too and that isnt really a shot even though its been intercepted by Butler and its clear that he was going to pass it on the other side.Those hands thrown up on air will really be just normal
specially if the ball had snatched out.Well, referee call do sucks sometimes but those are crucial moments.
Wondering if he would able to do it even more on game 5 to close the series.
Celtics would surely have adjustments and might able to stretch it to make it on game 6 through 7.Gap point isnt really that far off to make out conclusion that they will able to win
surely on game 5.
