One more pic, the quarterback requested.

Flanked by his three top receivers, Tua Tagovailoa wasn’t ready to finish the postgame iPhone photo shoot on the Alabama sideline. As Rammer Jammer wailed in the background, the four mugged for one more shot. This was one to remember.

Maybe an hour earlier, Tagovailoa, Henry Ruggs III, DeVonta Smith and Jerry Jeudy combined for a season-defining 15 minutes and 31 seconds.

It might just have been Tagovailoa’s Heisman moment.

The sophomore quarterback’s electric third quarter helped push his Crimson Tide to a 52-21 Iron Bowl win over Auburn after a sluggish first half. His six total touchdowns broke a school record while the five he threw equaled a school mark.

The second half was on another level. Completing 11 of 12 passes for 208 yards and four touchdowns, Tagovailoa and his receivers turned a tight game with lagging energy into a rout.

“Don’t ask me why,” Saban said, “but it didn’t seem like we had the right kind of energy in the first half.”

Auburn defensive coordinator Kevin Steele -- previously at Alabama -- did a good job of mixing and disguising coverages, Tagovailoa said. It wasn’t different from the film, just well camouflaged.

Tagovailoa, who was 25-for-32 for 324 yards passing, described a calm halftime scene despite the uneven performance. It wasn’t bad, just not elite as passes missed open targets while a blocked punt set up a quick Auburn score. It was 17-14 and the elements for an upset were simmering.

“Some of us listen to what Saban says and some of us are talking to each other,” Tagovailoa said. “I fell into the category of talking to my teammates. So, I didn’t really get to hear what Coach Saban was saying but every time he gives one of those woo-rah speeches, it’s one of those things were you listen to the tone instead of message.”

It must have worked.

The first drive of the second half took all of five plays to go 75 yards -- the last 46 of which went to Jeudy.

Tagovailoa explained what happened that moment.

“We saw they were always looking to the sideline,” he said, “and we knew that if we hurried up, tempo you know, we would have an opportunity to take a shot. Before they got set, we ran the play.”

An Auburn three-and-out set up the next quick march. Four plays, 69 yards and a 33-yard touchdown pass to running back Josh Jacobs. Just over five minutes ticked off the second-half clock and Alabama had a comfortable 31-14 lead.

And when Auburn punched back with a 10-play touchdown drive, Tagovailoa and Alabama had a hasty response.

Three plays, 75 yards. This touchdown went to DeVonta Smith -- a 40-yarder with a juke move and a seal block from Ruggs. A drive later, it was Ruggs completing the sophomore-receiver touchdown cycle with a 22-yarder from Tagovailoa.

It was 45-21 and Tagovailoa’s night ended 31 seconds into the fourth quarter.

“He doesn’t ever seem to get flustered in the game,” Saban said. “Things don’t go well, he misses a couple of passes, whatever. He always seems to respond exactly how you’d like a quarterback to respond.”

And Tagovailoa is quick with a response to every question he faced in the postgame, except for one. Saban said his quarterback hates to lose and Tagovailoa was asked how his coach would know. He’s unbeaten as a starter.

“It’s a secret,” Tagovailoa said after his 12th win in 12 tries.

From here, it’s back to Atlanta where Tagovailoa’s legend wrote the first chapter almost 11 months ago.

First, he got a few smart phone pics to remember an Iron Bowl win punctuated by a signature second-half outburst.
