ARod is a great play designer. He has plays that are unique, creative and when executed do quite well.
ARod is not a great play caller. Now to be fair somebody who can design a great play and call a great game is generally a head coach. There are maybe a handful of guys who are still coord that do both but off the top of my head, Ben Johnson of the Lions is about the only one I can think of that does both and still isn't a HC. ARod simply makes too many MAJOR mistakes in his play calling. Every OC makes mistakes, but you rarely see the commentary on 2-3 plays a game that you get on a Roderick called game.
Where you are taking a 5 year average, if you're gonna include 2020 to better fit your story, you may as well address the bigger issue: first 3 years calling plays, average is better than 10, last 2 years it's worse than 70 so basically took us back to the Detmer, early Grimes era. Whether he's there because he hasn't recruited or developed a QB or whether he allowed Funk to stay or people have figured him out, he's gotten progressively worse. To his credit, he has bounced back some this year. 48th is pretty good
But,to his detriment, Saturday was his first major egg this season. SMU and Utah have really good defenses and there's a narrative there to explain why BYU struggled in those games. Kansas does not. ARod stunk it up with 3rd down calls and red zone calls on Saturday. He's been bad with 3rd downs all year, but Saturday was epic in pressure play calling. You aren't a great play caller if you're sub 100 in 3rd down offense 2 years in a row. You're just not. I'm not calling for his head, but if he dials up a similar game plan Saturday and we fade down the stretch, I honestly think it puts him back on notice going into next season which might be unfair based on the season the team is having. But it is because he is the weakest link on the coaching staff at this point and you can't really get around that.
