It's not one game though. Some people have it and others don't. That was one of the most egregious examples of not having it I've ever seen. What a ridiculously weak minded and spirited person. Crumbled literal hours before he had too.
Honestly I think just about every offensive coordinator has had a bad showing play calling wise. If you was the team offensive coordinator we probably be judging you for your playcalling too. Kyle Shanahan is known as one of the better offensive minds in the league and yet there are some or more than some that states that he chokes during the big game given how things happen in the Superbowl when he was the playcaller for the Falcon years back against the patriots and in the super bowl against the chiefs some year back as well.
Even in the game against the ravens last year there were some if not more than some 49ers fans questioning why Kyle Shanahan didn't run the ball more .I feel like we expect perfection out our coaching staff and even players which is understandable but these guys are human beings. This was legit Monken first time calling plays in the playoffs especially in a AFC championship game ever in his career even at his age. I don't think Monken gets enough credit on how good of job he really did last year. He was able to move to another city/state to be the offensive coordinator for this team, he had to take on offensive concepts that was previously left by Greg Roman, and he had to totally adjust to new players but yet was still able to help Lamar Jackson reach to a potentially second MVP award. With all the praise Mike MacDonald has received even he wasn't as good of a play caller in his first year compared to his second year.
