If we know one thing about college football, we know that Jim Harbaugh is one of the most frequently discussed topics in the sport. Since his return to Michigan in 2015, Harbaugh has made no shortage of headlines.Through three seasons at his alma mater, Harbaugh is 28-11. After back-to-back 10-3 seasons in 2015 and 2016, he went 8-5 last year, finishing fourth in the Big Ten East. Harbaugh is also just 1-5 against rivals Ohio State and Michigan State.Michigan fans are still very much in Harbaugh’s corner, but questions have arisen about when his team will finally take the next step. Count FS1’s Jason Whitlock among those wondering.During a conversation with Colin Cowherd, Jason McIntyre and Geoff Schwartz on Speak For Yourself, Whitlock called out Harbaugh for being a disappointment.“He’s been a failure so far at Michigan,” Whitlock said. Pressed by Cowherd about whether 10 -win seasons in the Big Ten is a failure, Whitlock responded “Third, third and fourth [in the Big Ten East]. Based off of expectations, Colin…I want to see the proof.”In fairness, Whitlock did say he thinks this is the year Michigan could take a big leap, citing QB transfer Shea Patterson as the reason. But overall, he is taking a wait-and-see approach to Harbaugh.“I actually think this year, with Shea Patterson–he is super talented–they should beat Ohio State this year and should contend for the Big Ten title with Shea Patterson,” Whitlock said. “It’s all there. But I want to see it. We anointed this guy and thought he was going to come in and run roughshod over everybody in college football because he took one team to the Super Bowl and lost.”You can watch all of Whitlock’s comments below.”Jim Harbaugh has been a failure so far at Michigan.” @WhitlockJason pic.twitter.com/DY7BQomdJ0— Speak For Yourself (@SFY) July 24, 2018Listen, what Whitlock said isn’t really anything new about Harbaugh. This topic has been debated ad nauseum all offseason.Our take is that Harbaugh can’t really be considered a failure when you consider what he’s done in terms of reestablishing Michigan’s brand and the ability he’s shown to reel in top recruits. However, have the results on the field been a little disappointing? Probably.This looks like a year he could turn it around though, as long as his team can survive a particularly rugged schedule.
