Jim Harbaugh and Paul Finebaum aren’t afraid to stir up a hornets’ nest, are they?

In the latest in a long line of fun shots toward one another, Harbaugh brought the thunder in his latest jab at Finebaum, calling him “Pete” and the “SEC water carrier” on Twitter.

We’re 99.9 percent sure he meant to call him Pete, too.

Recently, Finebaum joined ESPN’s Outside the Lines and criticized Harbaugh for hiring California high school coach Michael Johnson, who happens to be the father of the top 2019 quarterback recruit.

“This is wrong,” Finebaum said (via Football Scoop). “It may not be illegal by NCAA standards and bylaws as of this moment, but to me it’s cheating. It’s blatantly disregarding the spirit of the NCAA rule. We all know why he’s doing it. And this is the same person who last year accused Nick Saban of cheating, he accused Hugh Freeze of cheating, and in my mind, and I know you can’t prove it and he won’t be penalized for it, but he’s cheating and why don’t we just face up to it? There’s no other reason why he would hire this man. It’s been done in the past… but it’s still wrong. I don’t know why the media celebrates Jim Harbaugh for disregarding the NCAA rule book and doing things that are in my mind unethical.”

But that’s nothing new. Finebaum has been somewhat of a Michigan hater since Harbaugh arrived, and he previously called him the Donald Trump of college football.

“But for whatever reason, the SEC coaches will not learn,” Finebaum said last year. “They have to keep reacting to this guy. It’s like Rubio and Kasich and Bush all reacting to Donald Trump. That’s what he wants. And the Donald Trump of college football, Jim Harbaugh, wants Greg Sankey and Hugh Freeze and Butch Jones and Gus Malzahn and Bret Bielema to all get their panties in a wad and make it an even a bigger story.”

Finebaum also bashed Michigan fans in December for being entitled.

“Michigan fans lately have been the worst,” Finebaum said in December. “Because they have won, let’s see, half a national championship in about 60 years, and they talk like they’re Alabama, Ohio State, [USC], Oklahoma, Nebraska, and Penn State wrapped into one.”

And Harbaugh has apparently had enough of it.
