I really like this article but I wouldn't agree with all the analysis - that's the beauty of this type of article - you can make up your own rumours and put forth your own opinion without ever having heard the rumour anywhere else.

So, here's my opinion...
Forsberg is staying put.  
Nabokov trade is not on - he and Toskala were told by coaches from the beginning of the year that they would be sharing duty all season long until the playoffs.
Samsonov could request a trade, but he is working hard to earn his way back up the lineup so that doesn't appear to be a possibility.
Gagne is going nowhere - you got that one right.
Alfredsson is the Captain and the leader of the Sens - no way will he be traded this season.  He's had a slow start, but that's no reason to trade him.
LeCavalier and St. Louis both have no trade clauses - they'd have to agree to the trade - don't look for that to happen soon.

The article definitely sparks debate - but rumours often do...
