Right now I like Latendresse. He's white hot in an environment where he is comfortable and playing with Marty Havlat. I might be wrong, but I think Kariya is hurt isn't he? Satan could be a good pickup, but it's a little early to tell. Umberger will singlehandedly kill your +/-.
On drops, Hecht is on a hot Buffalo team, so keep him. I know Upshall was hurt, not sure about anymore though. I don't know a ton about those guys though.
Myers, who is pretty hot might be a good pickup for Goli, who seems to be cooled down as of late.
