Rotational play or axial play? It shouldn't move along the lens axis. Mine also wiggles a tad rotationally (limited by the locking pin). If it's rotational and the play is minimal, then it's a tolerance stackup issue that is inherent in any manufactured process. My 70-200 also seems the "loosest" of all my lenses. Try moving the mount ring on your camera and lens with the lens off. It it moves at all, then you would want to tighten it or have someone take a look.

I think I know what you're talking about.
My 70-200 ii on my 5diii "moves" a little when i gently jiggle the camera(lens facing down). i've determined that the cause is some rotational play at the mount..even though this rotation is less than a millimeter. I've gone to three different camera stores and tried the same combo at each (and on the 5dii also) the little bit of "play" is there on every one them, some more than others. (I also checked the nikon 70-200 on a d700- it also had some play) So I've tried 7 or 8 different combos including the nikon and they all exhibit some of this "wiggle" or "play" if you gently shake them(lens pointed down) and/or move them in a certain direction suddenly..I also tried a sigma 70-200 on a 5d3 body and it did the same thing.
what i did to ease my mind is this....I held the camera and lens in my hands and twisted(rotated) the lens(gently) while holding the body still....this is how i determined mine had a little rotational play.(and every one of the others mentioned above) I then tried (ever so gently) to push and pull the lens away from the body....it did not move like it did in a rotational way.
if your combo has a little rotational play and the images are sharp...then you have a normal situation.
If your combo can be push / pulled even just a little bit, then you may have a problem.
I'm not an expert at this stuff by any means, but I have spent considerable time reading and learning about this issue.
Good luck.
