I think Frank and the OC knew his strengths and weaknesses and didn't put in too many plays that they knew Rivers would have a hard time executing. They did let him take a deep(ish) shot sometimes. I'm not sure they were overly conservative at all.
Rodgers only has himself to blame for not running that ball in on 3rd down. He had a clear lane to the EZ.
The decision to go for it should have been mostly irrelevant because 4th down wouldn’t have happened if he did run. And if he doesn’t get there...it’s going to be 4th and short...which makes the case for going for it even stronger.
Rodgers is a great QB...but he made a critical mistake.
