Not as bad as suggested by the criticism here. We've got a weak OL. OK should have recognized that from the start, but didn't. They adjusted and put extra pressure on the OL, and press coverage to take away quick screens. The way to beat that is with a quick, accurate and decisive QB and big, strong receivers that can be into their routes quickly and go up and get the ball from a smaller corner. Without that, there's not much the coaches can do.
Similarly, I agree it was a mistake to kick the FG on 4th & goal, but in the coaches defense, we're again talking about a weak OL trying to punch it in against a strong defensive front ready to make a stand. With a stronger OL, it's a no-brainer. With ours...
