DK Sports brought up a very valid point that I hadn't thought of in terms of leverage the Steelers have in that they would be helping the 49'ers salary cap by absorbing his contract. I can see the ruthless Khan artist telling John Lynch "I'll absorb half of his salary...you're welcome"
My preference is to stay put with what the Steelers have and let's see where this offense is. Van Jefferson knows his role in this offense as a #2 WR, CAIII has been said to have tightened up his route running and perhaps he takes on that role as the slot/possession guy? Pickens has a hell of a catch radius but from what I've seen in a handful of videos he is still covered and relies on the circus catch rather than improving his footwork and speed to get open. Or maybe the Steelers corners are that damn good!? Here's to hoping that is the case.
