Because Butker is a rookie and missed his first FG that could have swung the game? Again, I'm not saying it would be the right decision, it's just the decision most front offices would make.
I want him to make the rest of the field goals, but it ended up maybe helping us? They would've had to go for a touchdown or at least a third down conversion or fourth down conversion if they were down by six. But being down by three they went for the field-goal instead. Hindsight luck, maybe we would've stopped them from scoring the touchdown? And maybe we score a TD, but either way, glad we did not force them to go for the touchdown and then them getting it.
