That's the only explanation for this:

Don't be surprised if the Brewers accelerate their transition this winter by trading shortstop J.J. Hardy and possibly first baseman Prince Fielder for multiple high-end prospects.

The demand for shortstops, in particular, is rising. Hardy, second in OPS only to the Marlins' Hanley Ramirez among NL shortstops, could bring a quality young starting pitcher — think Giants right-hander Matt Cain — if he is packaged with the right youngsters.

J.J. Hardy is a nice player, sure.  But the centerpiece of a deal for Matt Cain?  Not a freakin' chance.
