How would Klint Kubiak's passing scheme , match up w/ our personnel? Any experts?

After watching five Vikings games, it seems Kubiak shares Shanahan’s preference for 12/21 personnel sets on early downs, particularly when running the ball. If he wants to run that here, he will likely be evaluating Johnson, Hill, and Prentice to see if they can be effective as the fifth skill player in his base run offense. Financial commitments to Johnson and Hill will likely put them on the field before we go shopping for replacements, but we can line them up in ways to give them easier blocking assignments and also benefit from any mismatches they find on those times we pass.

In those games, Kubiak ran 63% of the time with <3 WR on early downs and passed 83% of the time with 3+ WR.
The thing is 21 was KK's 1st full season as OC , His only playcalling experience prior to that was pre-season. That was 2yrs ago and I'm sure a learning experience just like ant 1st time OC. So what you are seeing in that 21 season may very well not be all we'll see from KK's play calling. PLUS having old school Zimmer as HC must have influenced KK's play calling
