Do we know for a fact that the Cards want to force a trade? Did the "report" come from Jurecki (who's referenced in a subsequent paragraph)? And, if not, what's the source?
The article was written as though it was hard news, but without a reliable source, and we could be being led down another primrose path along the same lines as the Peyton Manning and 95% Andy Reid rumors. With Jurecki, you never know - sometimes he has insider info, but sometimes he'll prematurely leap on an agent's leak or merely want to stir up buzz.
One thing seems logical - If I were Palmer's agent, I'd love to plant that story because it increases my leverage with the Raiders, the Cardinals and anyone else who has interest in Carson. UPDATE - Apparently, Jurecki is, in fact, the original source for the various accounts which are starting to sprout up like Spring daffodills.
