I think some changes will be made in the roster by the end of training camp. I expect both Fall and Robert Williams to make the team, if things continue in the summer league as they have the first two games. Yabu could be eating his way out of a job, and there are another couple players on that 15 man roster who are expendable for bigger players up front. It's possible Fall will wind up in Maine with a protected contract-- Austin Ainge signed him and really likes him, as many others do. He has become the fans' star of the summer league.
Danny hasn't been very active in trades so far this pre-season compared to some teams. I thought he missed the boat on Horford, but giving him 4 years would have been unwise. Philly will suffer that contract. I think he made a good signing in Kanter, but he's still weak up front compared to other teams.Theis is a 4, not a 5. The two 7 footers, Robert and Fall, could make the team if Danny wants to shift some emphasis to the inside. Robert is not a 7 footer, but he plays like one. I think more emphasis on the inside will be necessary for the Celtics to take the next step.
