Ronald Curry calling plays

My goodness, this is just too ridiculous. He called plays in ONE pre-season game and he was meh. He was in the offensive room when we had issues and what great idea did he contribute to turn it around? He was/ is part of the problem. He had 2 yrs under Harbaugh when they were awful and he's been here ever since . HARD PASS
Why would it be so ridiculous?? How much more experience do these other QB coaches and passing game coordinators have over Ronald Curry let's be real about it? Curry played 8yrs, has coached for 11yrs, and was NOMINATED to OC the Sr Bowl, what about some of the other candidates?
