re: So if Canada runs offense and Aranda runs defense. . .what does Coach O do exactly?

I may be wrong but now a days every football team (NCAA and NFL) has an OC and a DC. On top of that almost every OC coaches/runs the offense and the DC coaches/runs the defense.

You have astutely pointed out something everyone else has failed to realize - Head Coaches aren't needed - imagine all the money that teams will save now by firing all of the Head Coaches!!!!

BRILLIANT!!!!!!!
