Saints will interview Mike McCarthy in person during this week, Jan. 20-Jan. 25 [Underhill: McCarthy would have to be the current favorite]

It's not lazy. The point is that the fact that older coaches win a lot of Super Bowls is no more a valid reason to hire and older coach and not hire a younger coach than not hiring coaches who have won prior Super Bowls because no coach has won a Super Bowl with two different teams. There are too many variables involved to show causation. At best you have correlation because the are variables like the fact that who your QB likely has the biggest influence on who wins the Super Bowl and often a coach doesn't get that franchise QB in two different jobs.

You just have to pick the guy you think is the best coach and there is no way that having won a Super Bowl with another team should be considered a bad thing.

There is a correlation. They retire. I'm not making it up. They literally retire instead of continuing to pursue a championship. That's why age is the giant factor. It's already hard to win one. It's much harder to to repeat with the same team (even with a franchise QB), but data indicates it's possible perhaps because of familiarity or time in program. It's proven to be insanely hard to do with another team. Those who have tried end up retiring before getting there. We can't ignore the time limitation that the data suggests that coaches attempting to win with a different team are up against.
