If the original attempt at blocking for the dribbler was my game I would be thinking "This is a good time for a multiple foul." I've never called one but this would be a great time to assess fouls on both blockers.
I might even be tempted to suggest to the battered coach that it is time to set up his own fence. "Run your two blockers into this." Oooops multiple fouls again.
I'm betting that if you called a multiple foul just once the coach would go nuts. Then you T and eject him, if appropriate.
Other wise, I think about two multiple foul calls and you wouldn't see that tactic for the rest of that coach's career, let alone the season.
That's a facet of the rules I've never used.
