(Photo by Gregory Shamus/Getty Images)It happened, everyone. Jim Harbaugh is taking direct shots at Nick Saban on Twitter. This afternoon, Saban went on a lengthy rant against satellite camps, which Harbaugh has been the loudest proponent of over the last two seasons. Saban mentioned Harbaugh directly during his screed, though he was fairly diplomatic when bringing up the Michigan head coach. From AL.com:“I’m not blaming Jim Harbaugh, I’m not saying anything about him,” Saban said. “I’m just saying it’s bad for college football. Jim Harbaugh can do whatever he wants to do. I’m not saying anything bad about him if he thinks that’s what’s best. There needs to be somebody that looks out for what’s best for the game, not what’s best for the Big 10 or what’s best for the SEC, or what’s best for Jim Harbaugh, but what’s best for the game of college football — the integrity of the game, the coaches, the players and the people that play it. That’s bigger than all of this.Apparently, that doesn’t matter to Harbaugh, who put an unnamed Saban on blast moments ago.“Amazing” to me- Alabama broke NCAA rules & now their HC is lecturing us on the possibility of rules being broken at camps. Truly “amazing.”— Coach Harbaugh (@CoachJim4UM) June 1, 2016Jim Harbaugh won’t stop until he’s taken shots at every single rival coach in the college football world.
