I didn't see the game, only read the Gametime Forum comments and stat line and that's enough.
NO quarterback could thrive behind that O line tonight
1) against a 49er D that was schemed and playing to wreck it, and
2) without a running game, and
3) with a game plan that offered no effective counters to what the 49ers were easily predicted to bring.
The stat line says six sacks - it doesn't record the pressures and hits.
After a while any quarterback gets rattled after taking that kind of abuse. To his credit, I don't see any comment about Stafford having a hissy fit - he gets up and keeps throwing. Fatigued and beat up, that's when he eventually makes mistakes. I can't hold that against him.
