for the same reason teams in football don't let the other team score when the situation dictates itself - like you are trailing by 1 and the team has the ball at your 10 w/2 minutes left. the logcial thing to do is let them score a td so they go up 8 - and you get the ball back - but no coach does this - and they ALWAYS lose the game
coaches don't do this for the 1 time in 10,000 that it happens and they lose the game becasue of it they say, "i told you so" ignoring the fact the other 9,999 times it would work
i saw Bilas with Few and Few is an idiot for saying what he said
MOST of the time the team that hits that last second trey wins the game in OT so not fouling is stupid
