Please help...authenticate Pro Bowl jersey, 1980-'82

[LandRunSports]

Here's the jersey of interest...

For that era ('80-'82), the spacing of "National" and the size of the numbers appear to be wider than usual (particularly on the front), on the ebay jersey.

Can anyone help confirm that this jersey is legit? Perhaps 1980 or 1981?

I have ruled out the 1982 Pro Bowl...

Not '81.

Awesome, thank you. That only leaves 1980, anyone?

To clarify, the video is from the game played on January 31, 1982.
