Don't know who you'd put on the floor to be absolutely certain you can make fouls. Can't be totally certain with an exhausted Pierce.
I didn't want them to foul previous, and the shot doesn't change my mind. You're playing the percentages, and I like the defensive option all day over an off-ball foul, for example, that I couldn't control. I'd rather have someone tie me from behind the arc then potentially turn the ballgame over to erratic foul shooters like Rondo and Baby, and to a lesser extent the Captain.
