If Carr plays Sunday this could be the turning point for the O-line

It is 100% coaching at this point. We must adapt or die.

Play calling doesn't help get the ball out faster. We shouldn't be holding the ball. Stop calling plays that take too long to develop.
Carr got hurt on a 3rd and 9 when the RB missed his block. That gave the right DE that extra fraction of a second to get home. Carr knew he needed 9 yards, so he waited.

How many times have we fans yelled and screamed about throwing 4 yard passes on 3rd and long? I know I have many many times in recent years. Thats the conservative playcalling we make so much fuss about.

Now as the overall game plan? You are 100% correct. We absolutely need the plan to be quick hitters. But come 3rd down, it is what it is. They made a point on NOF's podcast that we ran the ball 13 times on first down and that 9 of those runs went for 1 yard or less. 3rd and long gives a huge advantage to the pass rush. The flip side is that OL has a huge advantage on run plays. THAT's where we need to start.
