Depends on the camera body; some bodies support Auto-focus fine tuning, others do not.can a 70 / 200 f2.8 lens be calibrated / fined tuned local guy at a camera shop does not think so
Then I don't see any reason you couldn't fine tune the Auto-focus on any lens you choose to.Its a D7100

Why did your local camera-shop-guy think it was not possible with your 70-200mm f/2.8?
EDIT: There are numerous methods to accomplish this end; I've used this simple setup as outlined by Nikon with great success:
How to Use the AF Fine Tune Function
@bikeit I think the confusion between the camera shop and here is what is being stated. Technically (without changing things mechanically) the "lens" cannot be fine tuned, but the D7100 can compensate ("Fine Tune") for the lens. I believe that the camera software basically can be set using the fine tuning (Don mentioned) to compensate for any "disagreement" between what the camera thinks is focus vs what the lens actually focuses on.
IOW the camera body is changed software wise to make the lens focus correctly.
Someone can correct me if I am all wet. Ha!
Got the lens fine tuned took a few tests shots at F2.8 and they are tack sharp, the guy was using the Reika Focal software, give me a full rundown before during and after, and all the print outs off the test he carried out.
Thats the one Don, he charged £30 for the first lens and £10 for all lens after that,
Just looked at that software, is it difficult to understand the process?
