I think this explains it all when it comes to Harbaugh and QBs!
So much to summarize but I will try. Because he played QB for so long and was really good, he had a unique prespective when watching film. He knew exactly where the QB's eyes should be focused for every play before the snap. Rich Gannon goes on to say how awesome it was to have him as his QB coach for only one year. He never got too technical, it was more about crowd Noise, etc. Gannon, who is now an announcer, also says that when he had meeting with Harbaugh before NFL games, he would get the most out of it because of how bright and outside the box he is. The kids he coached in college go on to say that Harbaugh is better with really smart QBs and that he probably will have a QB coach beside himself.......there is a lot more ...all really informative too
