What is really confounding is that there are some situations where the images are perfectly sharp. Here are three screenshots, zoomed in, showing three different apertures.
Screenshots are not really helpful in evaluating the IQ of images.
I see that you are using AI Servo focusing. Which AF point(s) are you using?
What drive mode are you using, One Shot or Continuous? If you are using Continuous Drive, then what are your 1st and 2nd Image priority settings? This last is crucial, because they control whether or not the camera can fire the shutter before it can lock focus.

" Here are three screenshots, zoomed in, showing three different apertures."
Which absolutely proves there is nothing wrong with the lens. The problem has to be with you. In the situation with the man you do not need Ai-servo. It probably just missed focus or as others have indicated motion blur. Sometimes it doesn't need over thinking.

Did you find out what needed fixed? Camera and/or Lens?
I am having similar issues as you described. It's been hard to explain that it's an intermitten issue, doesn't happen every shot, and that I know it's not user error...although I was hoping it was me, as it would be MUCH easier and cheaper to fix my brain than continue to do tests that don't explain the issue. *deep breath*
I've done tests on tripod, 100iso, different bodies, different lenses, etc. Nothing seems to show me the reason for the intermitten blurry images I see on my monitor when home from a shoot(outdoor senior sessions).
I just want to know if I should send in my lens...or if my camera(new 7 months ago) needs to be sent back. I MISS MY LOCAL CAMERA STORE SOOOO MUCH!!
Body is 6dii and lens that i use for senior sessions is 70-200 2.8 L USM Shutter speeds/settings are fast enough that there should not be this blurring problem. I guess I need to find myself a test subject and go out to test withOUT having camera on tripod. Urgh...this is super hard to explain... again, I WISH it was user error.
THANK YOU IN ADVANCE for sharing your experience/outcome with what sounds like a very very similar issue!!

Hi kaylyn. Welcome to the fporum.
Can you post one or two problem images to DropBox or OneDrive with a link here so we can see what you are seeing?
