Intentional Fouls

[secondyear]

At the end of the game when the team that is behind in points is trying to stop the clock, would you consider a player lowering his shoulder, without a play on the ball, and running into the dribbler an intentional foul? From my angle, I felt it was intentional all the way and received a raised eyebrow from the veteran official I was working with when I called the intentional foul. Without seeing the play, any thoughts from the board?
