As Leslie Frazier sauntered off the practice field Wednesday, he was reminded where this week's business trip was headed: Soldier Field in Chicago, the mere mention of which flipped a switch in his eyes.
"Bears week," the Vikings coach said with a grin.
This won't be the first time the former Bears cornerback returns as a coach. Frazier made the journey seven times as an assistant.
Mike Singletary, a Pro Football Hall of Famer as a Bears linebacker and now Frazier's linebackers coach, also has been down this road, coaching in Soldier Field in 2006 as the 49ers defensive coordinator.
A sense of nostalgia remains for the two as they prepare for Sunday night. Their close friendship began in Chicago in 1981 when both were rookies, blossoming when they both started for the celebrated '85 Bears defense, the one that dominated all comers on the way to a Super Bowl title.
Last week, that team finally made it to the White House to be honored as champions, a celebration postponed in early 1986 because of the Space Shuttle Challenger disaster.
"Everybody I heard from said it was an incredible experience," Frazier said. "It was something we all hoped to experience at some point. I wish I could have been there. But I had other work to tend to."
Added Singletary: "You don't know how special something is until you're removed from it. I had no idea at the time that group was as special as it was."
