He might be on the verge. This week will be crucial. If he comes up with another pedestrian game plan and the Rams game goes poorly, this season could go in the tank in a big hurry.
Every team has injuries but good coaches figure out a way to maintain functional levels of performance. The total failure of Harbaugh and Roman to put a reasonable (doesn't need to be great) passing game on the field in excusable, IMO. Yes the receivers are not winning one-on-one battles but the route patterns and combinations they are running are so simple a high school team could defend them. Thursday night Alex Smith completed 3 key 3rd down passes to 3rd string receivers for first downs. Andy Reid had put together some route patterns that allowed even the Bearded Wonder TE to get open. A good coach does that. He figures out how to make the players he has effective. That is what Harbaugh has to do. Dump his tricks and gimmicks and all the movement, and put in plays that let the players he has be successful.
