Int. Foul

[hbioteach]

Boys Frosh.

Team B down by 5 points 1:30 left with only 2 team fouls.
Team B is fouling to try to get 7 team fouls. First 3 fouls are good fouls going after the ball. B1 hugs A1 after inbounds pass. No attempt to play the ball. Int. foul on b1, 2 shots and the ball. What do you think?

In general, where should int. foul be called in the end of game situations. SHirt grab and breakaway fouls of course.
