The Los Angeles Rams fired Jeff Fisher on Monday and the Jim Harbaugh rumors began to swirl almost immediately. Any time an NFL coaching vacancy opens up, Harbaugh's name gets tossed around, but with the Rams opening there will be continual chatter about the Michigan coach until the job is filled.

Harbaugh's affection for the West Coast and specifically California is well known. If the combination of an NFL job opening in California wasn't enough to convince you that Harbaugh may have interest, let me tell you that Rams legend Eric Dickerson followed Harbaugh on Twitter on Monday -- his second most recent follow is Julia Louis-Dreyfus, who should absolutely get an interview for the Rams coaching job.

So now you have the perfect storm -- NFL job, California, Eric Dickerson's Twitter, a monster at running back in Todd Gurley -- for at least getting Harbaugh's attention, but I'm here to tell you four reasons why Slim Jimmy won't be leaving Ann Arbor any time soon for another return trip to the NFL, even for La La Land.

1. Harbaugh already makes NFL money: Jim Harbaugh is the highest paid college football coach and raked in $9 million in 2016, and he will go back to making $7 million per season through 2021 beginning next year. Jeff Fisher made $7 million a year and was among the NFL's highest paid coaches, so for the Rams to convince Harbaugh to jump back in it would take a substantial amount more than they were already doling out for Fisher.

2. He's scratched the NFL itch and been successful: College coaches always want to prove that they can succeed at the NFL level. You so often hear that coaches get "the NFL itch" and that desire to prove themselves at the highest level of the sport drives them to the NFL. I'm not sure that still exists with Harbaugh, who proved his abilities in the NFL by taking the 49ers to one Super Bowl and three NFC title games in four seasons with a 44-19-1 record. There's not a whole lot more he can do, aside from win a Super Bowl -- which certainly could still be something he really wants to do as a coach. Does that dream outweigh his desire to bring a national title to his alma mater? I'd be surprised if the answer there is yes.

3. College football is a better long-term fit for his style than the NFL: The thing you continually heard at the end of Harbaugh's tenure with the 49ers in San Francisco was that he'd worn out his welcome with both players and the front office. Harbaugh can coach in the NFL and be successful, of that there is no doubt, but his style wears people out. That's why being a college coach makes more sense for Harbaugh to keep a job long-term.

At Michigan, he pretty much has autonomy over his program, which keeps him from butting heads with any ownership above him or personnel people that have decision-making power over him. He also doesn't have to worry about his message and coaching style wearing out players because they all leave after three to five years anyway.

4. He's at Michigan: If Harbaugh were at any other school I'd say the three points above could be made moot. Stan Kroenke can dig in those pockets and find $10 million a year. Getting so close to winning a Super Bowl and falling short has to still eat at him, and there's no way, despite me thinking it's important and true, that he really thinks about his style not fitting in with the NFL for an extended period of time.

But he's not at any other school. Harbaugh is at his alma mater and wants to make Michigan's football program a national powerhouse again. He wants to wake up the echoes and return Michigan to the days of Bo, and I really don't think he will be tempted to leave this early in the process.
