Sixers TV analyst Marc Jackson joined the Dennis & Callahan show on Friday morning to talk about the Game 7 matchup between the 76ers and Celtics coming up on Saturday. To hear the interview, go to the Dennis & Callahan audio on demand page. 
Jackson said Kevin Garnett  needs to make a change in his game for the Celtics to emerge victorious.
“For Boston to win this game, KG has to get back on that block,” Jackson said. “Not necessarily settling for pick and pops or jump shots. But if you noticed the games that Philadelphia struggled with Boston were when KG imposed his will on the lower block. KG may be older in age, but he still has incredible skill on that block and he’s one of the best at seeing out of double teams. Even though Lavoy Allen  has played tremendous defense on KG, KG has to go back to the old KG and put him in the grinder and get it done.”
Jackson said Philadelphia will be up to the challenge of a Game 7 in Boston.
“Yes, Philadelphia towards the end of the year was winning more games on the road then in their own arena,” Jackson said. “They are young so they don’t really know what’s at stake here almost to a fault. But even if they are playing in Boston or playing in Philadelphia, it’s all the same to them. I think Boston has made a terrible mistake by not trying to finish the Sixers off early, because the longer you let the young guys stay around the more confident they get. And I know the 76ers are extremely confident that they can go into this game and win against the Boston Celtics  in their own court.”
Asked who he thought was going to be the one guy to step up for the Sixers, Jackson responded with Andre Iguodala .
“I’m going to say Andre Iguodala because of his defense, his swarming defense and the way he’s played defense on Paul Pierce , and before Paul it was Luol Deng,” Jackson said. “I know Paul made the comment earlier in the series that it’s not because Andre’s shutting him down but because the Sixers are playing great team defense. Paul, I love you to death, but I don’t want to hear that. Andre Iguodala has played great defense on you.”
Turning his attention to the bench, Jackson said coach Doug Collins  deserves a majority of the credit for the eighth-seeded Sixers’ success.
“He imposed his philosophy on defense first, sharing the ball, commitment to doing the right thing at all times … and that team has taken that philosophy and ran with it,” Jackson said. “If you hear everyone speak about Philadelphia, the first thing they say is that they like each other. Now, for people from the outside world who have never played professional sports, that’s a major key, because a lot of teams, believe or not, do not like each other. … The 76ers have no [bitterness].”
