The Shaq signing didn't scare me or bother me. Certainly Parker isn't a big deal. And while I don't think that Moon is a particularly special or valuable individual player, his addition to the Cavs pushes their TEAM up a notch or two for me. Rather than LeBron and a bunch of scrubs (still love you, Delonte!), the Cavs now look like a real basketball team. I still don't think they have enough talent surrounding LeBron, but I'm a little more intimidated by the Cavs now than I was before Moon signed.
EDIT: ...but I still like Boston against this new Cavs lineup.
