Was he actually watching the game?
They had FOUR players on the defensive glass, as you should in that scenario.
So you have to immediately secure the board and INSTANTLY get it to your point or whoever else can put enough touch on the fullcourt pass. The Hawks did neither and that was immediately clear when Collins got the board.
The head coach, especially run who ran point for 12 years and coached for another 14, should be able to instantly make that read and call the timeout.
Sounds like he predetermined that he was gonna run after a miss, which again isn’t the best route considering you already have to crash the glass in that scenario.
Long winded way of saying, yet another poor coaching move from this guy.
