its not about the yards it s the YPA, that is what you should be focusing on.
If a passer is getting 8+ypa that is pretty good and will take that all year. When you throw ball around 25 times per game you are not going to throw for over 300 yards.
BTW go look at the over all QBR and find more reason to gripe!
Sorry you have Taylor on your FFL and want the big fantasy numbers.
