That lineup is a good a guess as any, though I'd switch Galli to SF and have SG be the most volatile position.
SG might be chandler, walker, or azubuike later on.
My prediction for the Knicks is a rough start and a very streaky team. When this team gets hot and shots fall, they can beat anyone by running them out of the building. I don't see any team being faster.
However, Knicks will likely be destroyed by structured teams with good defense and bigs like the Lakers/Magic.
Look for the team to keep improving and if Dantoni can finally decide on a lineup, make a run for the playoffs after all star break. I'm sure we're not done making moves either.
