4 reasons Bears need to go all-in and hire Jim Harbaugh to fix everything

As the Chicago Bears get closer to making some of their key offseason decisions, one of those decisions looms larger than any other: what happens with quarterback Justin Fields?

But this isn't about Justin Fields. This is about arguably the second-most important question for the Bears: do they retain head coach Matt Eberflus?

Eberflus showed improvement this season, but is he really better than some of the other names available to Chicago? Specifically, is he a better fit than National Champion Jim Harbaugh?

The Michigan head coach very well could be on his way back to the NFL after winning a title Monday night, and he could be the answer the Bears have long-needed. Why should the Bears hire him?

1. His résumé speaks for itself

You simply cannot argue with the man's accomplishments.

Harbaugh turned around a San Diego program that wound up winning a championship in his second season with the team. At Stanford, he lead them to their first 11-win season in program history, a no. 4 BCS ranking and dominated Virginia Tech 40-12 in the Orange Bowl.

He then led the San Francisco 49ers to an NFC Championship a season after the team went 6-10. Harbaugh followed that up with a Super Bowl appearance in the next season.

Then, of course, he went on to Michigan to become a National Champion.

Harbaugh has been there and done that, as they say. He has been a winner, regardless of where he's been. If the Bears want to chance it on Eberflus or on an up-and-coming coaching candidate, fine. But, if they want a proven commodity, then Harbaugh is their guy.
