Very good article. I have recently got into this very discussion with some high school coach friends of mine, many of whom said they would refuse to foul because you could lose the game in regulation, whereas if you don't foul and someone hits the 3, you at least get overtime.
For instance, say you foul purposely and give them 2 free throws. They make the first one. Now, after missing the 2nd one on purpose, someone tips the ball out and it winds up in the hands of a shooter behind the arc, he hits the shot to put his team up by 1 and they win the game in regulation.
So, I guess you have to ask yourself which is more likely given the opposition's personel. A make, then miss, free throw, tipped out to an open shooter, and oh, by the way, he makes it at the buzzer for a 4 point play within 3 seconds to win the game. Or do you not foul and give up a 3 to tie the game and go into overtime.
I say Pearl made the right decision and anyone that doesn't foul is being a fool...
