That detail surprised me, I didn't think he would draw up a diagram like that. He has a lot of flaws but he's an impulsive numbskull with his head full of football and family. I like a main character who can admit that and work towards fixing himself.
Unlike everyone else, who just mope around while keeping him guessing without explaining anything.
Obviously he had his own plan during the match, which everyone else seems to ignore.
What's "natural" to you might not be natural to everyone else.
