Aside from being a great offensive coordinator and (now) good head coach, Lane Kiffin is known for poking fun at his former boss, Nick Saban.

Recently, author James Andrew Miller did a deep-dive on his popular Origins podcast about Nick Saban, and the second episode was released Monday. The podcast features the likes of Kiffin, Terry Saban, Scott Cochran, Joe Girardi, Barrett Jones and Greg McElroy.

Kiffin, of course, was relieved of his duties at Alabama before the Tide’s 2017 national championship game against Clemson — a game Alabama lost 35-31 with Steve Sarkisian as its offensive coordinator. Kiffin and Saban haven’t released details of the exact reason Kiffin left, and they probably never will.

On Episode 2, Miller indicated that Saban and Kiffin disagreed about how hard players should practice down the stretch of the season, and although Kiffin wouldn’t comment on details, he did explain how Saban changed that ultimately helped the Tide win another championship.

“I will say this, and I’ll give him (Saban) credit,” Kiffin said. “This last post-season that just came up after losing to Auburn and not making the SEC Championship — and this is documented by people who have said this, that he did change. So, to give him credit — I wish it would have been years before, but he did finally back off on those Playoff practices and won the national championship because of it. With an extremely close game in the championship, that would have been the difference. So, he cut back on practice reps that month leading up until the first game and then the week for the second game for the championship, and it paid off. I’ve spoken to players and coaches that could totally tell a difference, and the players felt a lot better. So, instead of focussing on the negative about why he didn’t do it when I was there, I’m going to focus on the positive that, ‘Hey, at least he eventually did it.’ So, bringing it up way back then eventually years later when I wasn’t there helped.”

The evolution of Nick Saban continues this day, and there’s no end in sight. He’s always looking for that edge, always prepared to make a major halftime change — Tua Tagovailoa — or risk to be a winner and always ready to tweak things that benefit players.

That’s just part of the reason why he’s likely the best coach in college football history.
