ELO? Everyone seems to be making up their own system these days.
Its funny though, when Tyrod was here, a lot of people used to love quoting ESPN’s QBR metric because he usually ranked pretty high there. Same with the regular NFL QB rating.
Now with Allen, those ratings are unreliable and controversial so we go with things like ELO where it looks like Allen is ranked higher. Admittedly though I’m not familiar with ELO or who created it.
