There was a point where Michigan coach Jim Harbaugh was the most polarizing figure in college football. While he’s still maybe the most talked about college football coach outside of Nick Saban and Dabo Swinney, it’s getting harder to find supporters. This week on the AP Top 25 College Football Podcast, AP sports writer Josh Dubow, who covered Harbaugh with Stanford and the 49ers and is a Michigan alum, joins Ralph Russo to do a deep dive on where things stand with the Wolverines and their coach. What is a fair assessment of Harbaugh’s tenure and is there realistic hope that he can deliver on the promise and hope that followed him when he arrived at his alma mater in 2015.Plus, what’s the status of Stanford football under David Shaw and why Josh spends hours a day battling Raiders’ fans on Twitter about David Carr.If you’d like to send questions or comments to be used on the show, email APTop25mailbag@gmail.com.Ralph’s Top 25 college football coaches: https://twitter.com/ralphDrussoAP/status/1376553969879818240
