Oh, absolutely, but not quite true either.
Yes, a great QB will get you over the hump, but sometimes having a good back-up QB helps too. See below:
- Roger Staubach (started season as back-up).
- Jim Plunkett (started season as back-up).
- Doug Williams (started season as back-up).
- Jeff Hostetler (replaced Phil Simms).
- Trent Dilfer (possibly the worst winning QB of the Super Bowl)
- Kurt Warner (started season as back-up).
- Tom FREAKIN' Brady (started season as back-up).
- Nick Foles (started season as back-up).
Sometimes you just need a good back-up QB just in case with a strong defense. We have Foles for another year (unless we cut/trade him). With that being said, I feel pretty good about Justin Fields + Nick Foles under a new HC/OC.
Trust me, I agree with you 99.9%, but the list proves that even the other 0.01% can be right.
