You act like a dearth of quality NFL QBs is something new.
No, I’m reiterating that it’s a continuing problem.
There have always been a lot of serviceable starters available and, every now and again, one of them catches lightning in a bottle and wins a Super Bowl (Hostetler, Dilfer, Foles, Favre etc)
Excellent 2nd half of your strawman.
If it's always been that way it's not a problem it's a simple reality.
And, that's not a strawman it's a fact. Teams do manage to put it all together with a less than average starter.
And sometimes a less than average starter comes in and puts together a magical season even if they don't win much. Jacoby Brissett is a great example of that. I bet the Colts would love to have him under center right about now.
