Jim Harbaugh's time in San Francisco seems to have a definitive timer on it, already making him the most coveted head football coach this season.

All reports seem to indicate that Harbaugh will leave the 49ers season is over, whether the organization fires him or he quits. While several sources believe Harbaugh will stay in the NFL one way or another, ESPN's Adam Schefter said the coach may be leaning toward the sizeable offer Michigan reportedly made him.

According to the Detroit Free Press, Schefter said on the show "NFL Insiders" that the Michigan job is a more likely landing spot for Harbagh now than it was last week.

"The more people you speak to about it, the more it seems as if Michigan is a landing spot for Jim Harbaugh," Schefter said. "We'll see how it shakes out, but the pendulum seems to have swung from him staying in the NFL to him perhaps going back to college. Again, it will be his decision; there's a lot that goes on. It's difficult sometimes to sift through all of this, when people have agendas, but the sense I'm getting is that Michigan is more in play today than it was a week or two weeks ago."

As MLive.com and the San Francisco Chronicle noted, Harbaugh has a strong personality. For Michigan, it is the reason they want him so bad and for the 49ers, it is the reason there is apparently friction between the front office and coaching staff.

Michigan, Harbaugh's alma mater and a proud football program to say the least, is coming off another disappointing season. The coach's intense approach is more fitting for college football and would be the kick the Wolverines need to get back on track.

Amidst season out of the playoff picture, with the franchise quarterback struggling, Harbaugh's approach to coaching seems to be wearing the front office thin. The 49ers have also looked considerably worse since losing in the Super Bowl two seasons ago.

"Well, as you know, I have not participated in the speculation, the unnamed sources or rumors or asked you to have Jay Glazer go back and ask his source for more clarification. I haven't participated and I don't intend to," Harbaugh said in a recent press conference. "This has been a good 12 months of this kind of thing. No reason to start right now... What will happen will happen, what won't happen won't happen. I work at the pleasure of the organization and let them have the floor on that."
