I just found this video with Celtics Coach Doc Rivers sitting down with the now retired legendary reporter Bob Ryan (aka: Grampa Celtic) at the Action for Boston Community Development 2nd Annual Hoop Dreams on September 13, 2012.
A couple of very interesting things here. First, Doc says that KG feels fantastic and that this is the best he has felt in years going into a season. (If I appear a bit giddy over this news, it's because I am.)
Doc discusses how moving KG to center made it so that teams struggled to guard us by putting 2 shooters at the four and five. He also explained that before the season he had stated 2 things that he would love to do. One was that KG was a five and he wanted to play him there but at the beginning of the season he didn't think he had another starting 4 so kept KG there. A second thing that he wanted to do was to find a starting 2 so that he could move Ray to the bench to give the bench a scoring boost.
At midseason, Jack Nolan, one of the Celtics' scouts, came to Doc and reminded him of what he had said before the season about moving KG to the 5 and bringing Ray off the bench. By that time, both Brandon and Avery had emerged and Doc was able to make the moves that he had envisioned before the season and it made the Celtics a better team. He's happy that JT (Jason Terry) wants to come off the bench this season and Courtney Lee will start to begin the season and when Avery comes back, "We'll see." Good stuff!!!
