But there is no sport that allows challenges of 'judgement call' penalties that I am aware of. If the chair decided a tennis player has misbehaved, they cannot challenge a penalty the chair imposes. If an NFL official calls a penalty the coach cannot challenge the penalty, if a soccer official gives a red card there is no challenge. All challenges in sports are based on incorrect identification of boundaries, touches, timing, etc. where technology can 'slow down the play' to clearly see what the eye might miss in real time. The judgement calls of officials are not challengeable.
And in reality it sure looked like a foul to me - a foul that is usually not called with time running out, but a foul. If instead of a loose ball in the back court situation it had been a shot attempt, would people have the same issue, or a rebound under the basket with a potential put-back?
And you are also saying officials should have different standards for different times in the game - so would the foul call have been acceptable if there were 10 seconds left, 2 minutes left? But a call with 2 minutes left would have altered the game situation completely at the 10 second mark and the 0.8 second mark anyway. If the official calls the sixth foul on Maya at the 2 minute mark, the whole game changes, so should they not call that foul?
