Well you got it all wrong here. As somebody said, all pixels are not equal. So if the pixel density is very high ( crop body with 24mp for example) you have a very big drop in shapness ( it's plain physics - difraction phenomenon mostly). So you might and up with that 300 pixels bird that looks mushy while on a FF body you get a 200 pixel bird that is very sharp and so it might take a resize to 300 pixels and still look better than your APS-C. Add noise into the equation and a crop from a FF sensor upscaled might look better than the APS-C equivalent without upscaling.

Given similar technologies, you will never get a drop in sharpness with a higher pixel density when the subject is viewed at the same magnification.    The larger pixel density will always yield the same or more likely more real subject detail, which means it will always have the same or more "reach".  This includes diffraction...at the same subject magnification, a denser sensor will always give you the same or more detail even when you're in the diffraction "zone".

I agree you can't really separate "portrait" cameras from "sports" these days.   I regularly used a D800 for sports and found it fantastic.   The ability to crop when I needed gave me far more flexibility and "reach" with the 70-200 without the frame crop restrictions of the D7000.   The lens was effectively "wider" than with the D7000 and had better "reach" than a with D700...the best of both.
