I'm sorry, but this thread is like preparing for a terminal illness that you don't know if and when it's going to arrive. Everyone here has thought about this, but tries not to DWELL on it. If it happens, it happens and we'll deal with it. They are not going to get some FA qb IMO, and we can only hope Kaep or the 'second coming of Joe Montana' Tolzien can step up if called upon. That's pretty much it, any further discussion is overanalyzing, since what people think they know about Kaep or Tolzien is pure speculation, other than meaningless preseason games.
The o-line does their job and we should be fine.
I'll be honest and say after a 5-1 start this thread was inevitable.
