Guys:
I don't think Givens' incompetent agent leaked the story directy to the Houston Chronicle. Rather, I think he probably told the Texans management that the Pats were making a "signficant offer" that Givens was likely to accept. Being incompetent, he probably assumed that Casserly would immediately respond with something like, "wait, we'll double it!"
Instead Casserly thanked Agent Blank for the call and later, while "leaking" other info to the newspaper reporter, included the tidbit that it looked like Givens was signing with the Pats.
I think Agent Blank is simply trying to create the illusion of big demand for his decent #2 wide receiver client. The reality may be that his decent #2 wide receiver is only seeing offers of decent #2 wide receiver money.
