TSN Canada has a good preview of the Celtics. He makes a lot of good points. Well worth the read.
What the Celtics want to avoid is what happens to a lot of bad teams, who live and die by their youth. They insist they have to develop them for the future, but often they do so without providing them any veteran leadership along the way. The key is in using the vets as augmentation to your youth, though, not as a replacement when they don't cut it. If your youth can't learn to win games on their own, then they aren't the future of your team, and shouldn't be kept around just for the sake of trying to prove your detractors wrong. There are already many critics out there who say that Ainge is overvaluing his young personnel, so how quickly the young guys can come on and prove that they can lead the team to some victories is paramount for the future of this organization, both on the court and off. If it turns out the only way these guys can get wins is to ride Pierce, Szczerbiak and Ratliff into the ground, then the future of this team (and its management) will be short lived indeed.
The Celtics have definitely given themselves options for the future, and the question now is which of these options make themselves valuable enough to keep around to help reconstruct this once proud franchise back to supremacy. [More] source: TSN.ca
