Never had this happen before.
A flagrant foul usually gives the team fouled free throws + possession.
However, this flagrant foul occurred with 0:00 time remaining in a quarter.
The offending team got the ball to start the next quarter (determined by the opening tip-off, so both teams get the ball to start 2 quarters each.)
Should the team that committed the flagrant foul lose possession to start the next quarter?
