Some high praise for JJ coming from Coach Jackson and Harrison, really shows how much they loved him and his impact on the team. Some noteworthy quotes: Asked his reaction to losing Jack to free agency, Jackson said, "It was torture because he's an incredible, incredible…forget about basketball. He's a great leader, loves the game, no nonsense. He had a great year for us. For me, he was a joy to coach, an absolute joy to coach, and I'll have a relationship with him for the rest of our lives.'' "He's going to help the culture,'' Jackson said. "He's going to help Mike Brown just as much as he helps Kyrie Irving. The things that he does to protect the locker room, to protect the team, to make sure that you're doing things the right way…he's just incredible. It was the best money that the Cavs could have ever spent.'' Golden State's Harrison Barnes, a good friend of Irving's, knows Jack will help the Cavs. "He was instrumental in me getting going and getting comfortable out there,'' said Barnes, who took in Monday's game and will be working out at the USA Basketball minicamp the rest of the week. "He was always positive and encouraging. Off the court, he was a good guy to hang out with. I think he'll help a lot. Jarrett is the ultimate professional, goes about his work very seriously. I think he'll get the most out of his guys.''
