This game is not played by robots.
If I'm the Giants, I'm ultra aggressive because I'm usually outmanned and outcoached. So I have to take chances throughout the game and hope enough of those plays go my way to steal a few wins.
If I'm the Chiefs, I don't have to be agressive at all. Why? Because I have Patrick friggin' Mahomes and a field full of playmakers that can get me out of any jam I might find myself in.
So if it's 4th and 6 on my 40 yard line, I go for it pretty much all the time if I'm the Giants. Sure I might lose a bunch of games 52-0, but if I make enough plays, I can win my share too.
If I'm the Chiefs I can do whaterver I want. For poops and giggles I can go for it knowing that if I don't make it, I will be fine because I still outman you. But I have no trouble punting either. I have a reasonably good defense and 10 to 12 plays drives can be tough to put together. I will probably win the game either way.
Those are the 2 extremes. My point is that what's right for one team may not be right for another. You cannot just ignore the human element that football presents.
