In Super Bowl XLIX, Keeping Alert for Trick Plays

Sports of The Times

By MICHAEL POWELL

PHOENIX — So you put the questions to the offensive and defensive coordinators whose fate it was to have spent the two weeks before the Super Bowl in a more or less constant state of sleepless agitation:

How far do other teams’ tricksters crawl into your cranium? Do you let such worries take nest in your cerebral cortex, the better to devise a counter, or do you try to banish the thoughts altogether?

Josh McDaniels, the crew-cut offensive coordinator for the New England Patriots, whose own innovations and tricks inflict so much pain on other teams, smiled. That way lies madness.

His therapist? This is an N.F.L. presser?

The master of unsettlement was next up. Belichick shrugged, and shrugged again. “I’ve had a couple ups and downs,” he said. “What doesn’t kill you makes you stronger.”

Mind game meets real game Sunday.
