In Buzzerbeater, a flagrant foul is two free throws and possession.
Thanks. I guess that if in the same sequence it is mentioned foul+flagrant foul it means it is just 1 foul, right?
Yes, basically the way I read it is that the announcers notice that there's a foul called and then the referee signals that it was flagrant. It's just a side effect of the way that the play-by-play is displayed a little at a time to try to mimic a regular game presentation.
