I think I would drop Doan or Hemsky for Semin.
I don't think I would drop Havlat. He's been pretty consistent all year long. Which is nice.
As for Vinny....yes. Drop Steen, get Vinny. He may not be the Vinny of old, but he's still pretty damned good, and is in a great PP situation in TB. If you can get him, don't think twice!
