The new coach of the 49ers in Jim Tomsula. The old coach was so toxic to the situation that he was not even on speaking terms with the new coach. As great as Jim Harbaugh was a coach, he must be the most impossible human being to work with. It appears that the 49ers were in such disarray that the front office had to get rid of Harbaugh before he was able to turn the entire team into a hurricane where in he was the eye. This might be why he only stays places for about four years. He spent four years at Stanford and then moved on. He was at San Diego four years before that, and that might be how long he can last.
With this new information, it is possible that Harbaugh will not be able to work out his whole contract at Michigan because he is such an abrasive personality. If it were just the 49ers, that would make sense, but he seems to move on from jobs quickly. If he is that hard to work with, we can only imagine how bad it will get up at Michigan.
