Just saw an inbounds with 26.2 in a 77-75 game (Utah lead and possession, baseline throw-in following a made basket).
After dribbling for nine seconds, Utah player throws the ball from the back court to the front court and the ball doesn't get touched (gain front court status) till 16.9, with a whistle for a foul to stop play simultaneously with the ball gaining front court status. However, the clock doesn't stopped till 15.6.
Help me understand why:
a. This is not a back court violation in NCAA Men's?
b. The officials don't clearly see that it was 26.2 and now 15.6?
c. This does not go to review to see: If the ball gained front court status in time or if the clock needed to be reset?
