All coaches second guess themselves or regret decisions they’ve made.

Nick Saban shared his biggest regret recently during an appearance on “The Pivot” podcast, and it would’ve changed the college football landscape for years.

“When I left LSU that was probably professionally the biggest mistake that I ever made,” he admitted.

Saban, who won a national championship at LSU, took the Miami Dolphins job before returning to college and leading Alabama to six more national titles.

He added the perceived lack of success at Miami didn’t lead him to that conclusion.

“I found out in that experience that I like coaching in college better because you could help players personally, academically, athletically and all of that a little more than in pro ball.”

Saban added he loved the status of coaching in the NFL and leading the best of the best against equal talent.

He shared a story, he said, he never shared before.

“I can’t go back to LSU,” he said. “Go to Alabama, and, no disrespect to Alabama, it’s not Alabama vs. LSU. It’s just (agent) Jimmy Sexton stood on the balcony when I was getting ready to leave LSU. … He said, ‘What do you want your legacy to be as a coach? Do you want to be Vince Lombardi, or do you want to be Bear Bryant?’

“Without hesitation, I said, ‘Bear Bryant.’

“He said, ‘What are you doing going to Miami then?’”

The rest, as they say, is history.
