The PAC had been horrible for a long time, but the PAC Homer voters have propped them up.
Yewts are a classic example - 4 losses including a blowout loss (by defacto 3 TDs) to the #3 team from another conference and they get ranked #10? It's not like they had a body of work before that to give them tailwinds: they haven't won a P4 game since 2017.
But it's the voters from that fifth P5 that keep homering the vote to keep PAC teams relevant.
I guess it wasn't enough though
