To this day, Bud Grant still can't answer the question. Neither can Rich Gannon or Bernie Kosar or Jon Gruden, or anyone else on the long list of luminaries who wonder why it took nearly 30 years for Marc Trestman to become a head coach in the NFL.
Trestman used to wonder, too, during 17 seasons as an NFL assistant with eight teams. But long before last January — when the discussion began anew, after he was hired at age 57 to coach the Chicago Bears — the St. Louis Park native had begun to see things in a new light. Fretting about his long wait wasn't going to get him any closer to his dream job. Instead, Trestman came to believe that each twist in his circuitous career path was molding him into a man worthy of leading an NFL team, sustaining his faith that he would eventually get there.
Armed with that fresh outlook, he stopped worrying about the end and put his mind to the means. Nine years removed from his last NFL job, Trestman has become a more outwardly focused person, guiding the Bears into Sunday's game against his hometown Vikings with a confident and compassionate hand.
His five-season tenure as a head coach in the Canadian Football League enhanced Trestman's reputation as an offensive savant known for his way with quarterbacks. That made him an intriguing choice for the offensively challenged Bears and underachieving signal-caller Jay Cutler. Trestman already has earned high praise from his players — and the game ball after a 24-21 victory over Cincinnati in his debut last week.
Some have considered the former Gophers quarterback an unusual fit in Chicago; reed-thin and bespectacled, with a scholarly manner and a self-help author's vocabulary, he comes off as the anti-Mike Ditka. None of that will matter if Trestman can lead the Bears to the playoffs for the first time since 2010. In that regard, they might be the perfect match: a franchise pining for an unfulfilled ambition, paired with a coach grateful for the chance to realize his own.
"Having looked back at the journey, I think I understand,'' Trestman said last month, just after the Bears broke camp. "I have a much better perspective on it now than I ever would have had if this had happened 10 or 12 years ago. The wait was very much worthwhile, because all those experiences go into making you the person you are and the coach you are.
"I have complete appreciation for this moment and respect for why it took so long. People say this all the time: If you want to get to where you want to go, just stay focused on what you're doing, put your heart into it and don't worry about the returns. This came, really, out of nowhere. But really, it came out of hope and passion.''
Not to mention persistence.
