Welcome to the Trade Rumor Mill: Check Your Sanity At the Door

It begins with a whisper on a blog then blossoms into something bigger.
Such and such player is going here.   This dude is going there.  In the area of journalism, the rumor and innuendo take some getting used to.
For instance the Cavaliers have supposedly asked about the availability of Antawn Jamison of the Washington Wizards according to one report.  Made a concerted effort to get Amar'e Stoudemire of the Phoenix Suns according to a myriad of others.  And now they are targeting Richard Jefferson  of the Milwaukee Bucks and his 18 points and 4.9 rebounds per game, according to Yahoo Sports.
The bait for Jefferson's services: Wally Szczerbiak's expiring contract which would get the Bucks some cap relief.  Jefferson has approximately $29 million left on his contract and the Cavs are one of few teams in a position of not having to worry about that issue.
But why would you do this deal if you're Milwaukee?  What's the upside other than freeing up money? They are in the hunt to play sacrificial lamb in the opening round of the playoffs. 
If you're the Cavaliers and you can do this deal - Szczerbiak for Jefferson - you take it and run cackling like a villain an a black-and-white western.  That's why it's likely nothing more than rumor - without another player it doesn't make sense.
There are tell tale signs that the Cavs are busy at something - what it is, no one has quite figured out yet.  Besides, they could be trying like hell to work out a deal but nothing pans out.  What is sure is that we will know approximately 12 hours from now.
