No, on the condition that John/Pete can show us some sign that they are going to properly invest and/or change their approach to the offensive line. They aren't perfect, but as long as they can show they're willing to learn from their mistakes, I still believe in their ability to build a contender.
If they can't do this, it shows they have a huge blind spot and are just trying the same thing over again and expecting different results. And in that scenerio, at some point, you need to make a change at the top. Long-term mediocrity is about the worst place for a team to be: not good enough to win it all, but not bad enough to force changes.
