Inside the huddles, Tannehill was showing nothing but calm and confidence.

“Same. Same. Same,” Bess described Tannehill’s demeanor. “Never rattled.”

“Extremely poised for a rookie,” added Bush.

“Comfortable,” said Clay.

There had been a funny episode along the way Sunday.

A computer glitch caused the stadium sprinklers to suddenly go on late in the third quarter, interrupting play and briefly soaking the field.

“Funniest thing ever,” linebacker Karlos Dansby called it later. “Never seen that before. Well, high school, maybe.”

Based on the fourth quarter that followed, we’ll call that brief shower Tannehill’s baptism.

What we saw was a young QB good enough to perform in the clutch when he has the right help.

There may come a time when he is experienced enough to do the heavy lifting even without much help, as the great ones do.

For now, Tannehill needs the solid offensive-line play he got Sunday. And he needs guys like Bess and Clay to make us forget Miami does not have a premier No. 1 receiver. And he needs a stout running game to also ease the burden — and certainly got that with 189 yards rushing, 87 of them by Reggie Bush.

“You saw some of those play-action passes working,” noted Bush of the impact of a great running game on the passing game’s success.

Tannehill would complete 11 of 15 passes for 185 yards in the second half. He would also break Marino’s 1983 rookie record for most passing yards in a season.

That record might seem like a major milestone, but the first career fourth-quarter comeback might have been an even bigger one.

See, it was that comeback that offered the very same message to the believers who found affirmation as it did to the doubters who maybe found renewed hope:

This kid is good enough.
