Well, I guess there's the running backs coach Kirby Wilson making comments around draft time.Pass protection isn't overrated when talking about rookies, but it is something people like to just make statements about without any real basis. Most people are just assuming that Aaiata is miles ahead of McKinnon in all these aspects of playing RB that aren't do do with athletic skill and running the football, or they assume that all rookies are hopeless in pass protection and anyone who isn't a rookie is good at it.
The point is you don't have to be Ahmad Bradshaw in pass protection to get playing time in the NFL - if you are competent, that can be enough. It's possible that McKinnon is getting there and isn't far behind Asiata at all. No one posting on here really knows. There are also
plays and situations where you can put a guy like McKinnon on the field that don't require those skills. I guess people are always concerned that a guy like McKinnon can't be an "every down" back, but how many of those are there anyway?
As far as McKinnon goes, I don't know what evidence there is to say he's brutal in pass protection. With some rookies, it's all you hear about initially (Montee Ball, Tre Mason), with others, fantasy owners don't seem to care whether they are good or bad at it (I don't recall seeing threads about Gio, Lacy or Doug Martin and their pass protection), and they get playing time anyway. It's not the same for every rookie and for all we know, Asiata won't have any glaring advantages over McKinnon in about a month.
If the Vikings intend to turn McKinnon into their version of Sproles ... they'll have to teach him plenty of new things. The first item on that list, Wilson said, would be pass protection

Then there's McKinnon himself a few months ago.
Vikings rookie RB Jerick McKinnon admits that he needs to improve as a pass blocker. “The only thing that’s a little bit different is the pass protection," McKinnon said. "I really hadn’t had any technique on it or been coached on it.

And lastly perhaps some notes from Day 3 of training camp give a few more hints.
Jerick McKinnon struggled to stop Anthony Barr off the edge and Kirby Wilson really was trying to enhance his blocking technique. This was a concern when the Vikings drafted McKinnon and is certainly an area he will need to improve upon.

So the concerns some have in this thread aren't totally unfounded.
