PHOENIX — Put Bill Belichick behind a microphone and he’s C-SPAN — minus the information.

Pete Carroll is more like a Lifetime movie. Or, as defensive lineman Michael Bennett puts it, “He has that Benjamin Button effect on everyone.”

The Super Bowl coaches approach their obligations to the public and media from opposite ends. Belichick, coaching for his fourth championship in New England, is dry, offers little to no insight and rarely makes anyone laugh. Carroll, looking for his second straight title, is a high-fiving, fist-bumping extrovert who started one of his news conferences this week with a welcoming, “What’s up?!?”

Different styles have produced similar results, though.

Belichick is making his sixth Super Bowl appearance as a head coach and his Patriots are as close as there is to a dynasty in the current NFL. Carroll’s team is being mentioned as a possible dynasty, as well, and that notion will only gain steam if the Seahawks win Sunday and become the first back-to-back champions since, who else?, New England in 2003-04.

Dissimilar as they are, they have both built their teams on a foundation of unflinching candor inside their locker and meeting rooms — a quality Carroll brings to some of his public speaking, but one that Belichick eschews.

“What you see on TV is what you get, pretty much, from the two,” said Patriots cornerback Brandon Browner, who previously played for Carroll in Seattle. “They have similarities too, though. Their football IQ is way up there. They are so different, but at the same time they’re the same. That’s why they both have succeeded at this level.”
