Boston Celtics coach Doc Rivers is still going on about the subject of restraint and mental toughness.  This topic has been in the spotlight ever since his Celtics lost to the Indiana Pacers in the first round of the Eastern Conference playoffs.  One particular incident involved Paul Pierce getting ejected after throwing an elbow to a Pacer player in crunch time after being fouled on the perimeter.

''Danny Fortson knocked down [Manu] Ginobili. And Ginobili got right back up, made the two free throws, and the Spurs won the game.

''To me, that's toughness," said the Celtics coach. ''I keep telling our guys that there's a big difference between being physical and playing aggressive and responding. If someone fouls you hard, you don't respond. You do what Ginobili did. You turn the other cheek, make the free throws and win the game. To me, turning the other cheek is much more of a sign of toughness than pushing back."
