Is Jim Harbaugh ready for prime time? I don’t think so. There were lots of reasons the 49ers lost to the Dallas Cowboys on Sunday, but Harbaugh was the main reason. Bad calls. Bad thinking. Bad game management. I think of that play when he had the wrong offensive lineman eligible. That was pure Mike Singletary goofy stuff. There was a lot more. The Niners lost and the loss is mostly on him. To read my column on Jim Harbaugh, rookie coach click here.
