Up 28-14 in the 4th qtr WE THREW THE BALL 22 MORE TIMES!. Point being it was unnecessary
We were never up by that with the ball. They never had the ball and a 2 score lead.
Passes tend to pile up late in halves/OT because of the clock.
But I checked, and you're numbers are wrong. They threw 13 more times. I think your 22 number is their total plays. So, 13 passes, 9 rushes. At least 3 passes were 3rd and long. One was the final "Hail Mary" dump it off to Turpin and see if he can make a play to end regulation (which followed a run).
Edit: Checking to verify, the team ran 23 plays after scoring their last TD. At play 18, it was an even split - 9 runs, 9 passes. At play 21, it would have been 10 rushes to 11 passes, but the carry on that play was called back for a holding penalty. That made it 2nd and 19. From that point, there were 3 pass plays (understandably).
The narrative isn't based on reality.
