As I tell my children, when you're losing an argument, the key is to improve your argument. You can throw a fit and call people names, but it won't help people take you more seriously.
Predictions will often be wrong, like most of yours this past season, as it's based on information we don't have. It's a thing we do for fun on message boards, and we've all made embarrassing picks in hindsight. Getting facts wrong about what has already happened is a lot harder to justify.
I rely a lot on advanced statistics, so it's hard to have a conversation with somebody that doesn't understand SP+, EPA, or even the difference between QBR and passer rating.
But anybody should be able to look up our traditional statistics and say that a true freshman has been RB3 or higher four times in the last four seasons under Demarco. So the notion that a true freshman can't be RB3 or higher under DeMarco is simply wrong. It's hilarious wrong when considering that our leading rusher from last year contributed from day 1 as a true freshman.
Take the L and find a different hill to die on. That is an indefensible stance.
