No.The three point shot you're referring to came after 4 straight fouls that put the opponent in the bonus. The very next foul, on the possession after the 3, sent him to the line. My point is prior to those 4 straight fouls, it was a 2 point game with over a minute left. There was no need to put him in the bonus. The 3 point shot he managed to squeeze out was inconsequential because it happened after what I'm saying was questionable coaching.
Think a second before to talk
The foul that sent your adevrsary to the line was after you were 5 point down and you miss the shot on 74-79,with your adversary grabbing the defensive rebound and 52 second left to the end
If in this score situation you still weren't in the bonus,you could not stop the clock quickly to try a comeback to win the game,because at that point you had to spend all the fouls to go in the bonus and then the foul to send him to the line,losing a lot of time.And you could not simply try to defend without a foul,because he was two possession ahead of you,and could slow the tempo to lose other time
Your coach decides on -2 and the ball in his hands to prepare for the situation that could happen in the future,with your team needing to stop the clock quickly with a higher disadvantage,as then effectively happens,and make a reasonable choice.
Your loss it's not due to a your coach mistake,but to a better adversary team in that match
