Rondo seems to be over his recent slump, and his play has got the coaching staff more than a little excited. WEEI reports: “In two games since taking a mental health day or resting an ailing pinky finger or whatever the heck kept Rajon Rondo from playing against the Timberwolves on Sunday, the Celtics point guard has produced 44 points on 20-of-33 shooting and 22 points against only one turnover. To make a long story short, Rondo is back. Rondo went through a five-game stretch in mid-March when he didn’t reach double figures in points or assists, causing many to question whether the absence of his pal Perkins had taken its toll mentally — a notion that in retrospect seems silly considering his aptitude and fortitude. Perhaps the greatest affirmation of Rondo’s return is the fact that he took nine shots from beyond nine feet — and knocked down six of them (66.7 percent). He entered the game shooting just 34.6 percent from 10-15 feet and 38.0 percent from 16-23 feet. ‘That was terrific,’ Celtics coach Doc Rivers told reporters. ‘Hell, I’m going to say it. I probably shouldn’t, but I call it coach’s porn. We kept moving the ball, and Rondo kept taking shots and I was yelling that jokingly to them. We were laughing, because we had a joke about it that I won’t get into. It was terrific.’ There you have it. Rondo performed so well that Rivers dubbed it ‘coach’s porn.’”
