Malzahn was coaching high school like five years ago.
True story! He maps his offensive plays with colored (not racist) sharpies, it's something we're not proud of. His wife is also bats hit (autocorrected) crazy!
Also, while Malzahn was coaching high school not too long ago, it's well known that HCBS is a long time middle school substitute. He's not the cool sub either, he's a hardass, demanding perfection when diagramming sentences*.
* true motivation for substitute teaching is to scope calf potential
