The easy storyline heading into this week was that Green Bay received a good "warmup" for 49ers quarterback Colin Kaepernick in last weekend's NFC wild card game against Minnesota with Joe Webb under center for the Vikings.
After all, Webb ran some of the same zone-read option plays that Kaepernick will, right?
"No, not really," Packers coach Mike McCarthy said in a conference call with Bay Area writers on Tuesday.
"I mean, Colin Kaepernick, to me, is a totally different player than Joe Webb. There's a play or two, schematically, that we've seen in the (Minnesota) game that carries over to some of the things we've seen on film from the 49ers. But Colin Kaepernick, just for the little time he has been a starter, is a little more experienced, a little more productive quarterback and he creates different challenges for us."
A reporter then asked McCarthy what was one thing he was stressing his defense to be aware of when it plays Kaepernick.
"Why the hell would I talk about that in a press conference?" McCarthy howled.
McCarthy, though, did expand somewhat on his experience as a one-time 49ers assistant. He was San Francisco's offensive coordinator in 2005, the year before Green Bay hired him as its head coach.
"Every experience you have as an assistant coach helps shape you and prepares you to be a head coach," McCarthy said. "The opportunity to work in San Francisco was really a great one for me personally, on a number of different fronts.
"As a young coach at the University of Pittsburgh (from 1989 through 1992), with Paul Hackett, we always studied the 49ers film and it was something that we were always trying to emulate. Then go to Kansas City (in 1993) and the six years that I was at Kansas City, all three quarterbacks had come from San Francisco. So you had a lot of time you spent being in touch with the way they did things out there, particularly on offense."
In 1999, McCarthy became the Packers quarterbacks coach before moving onto New Orleans as the Saints offensive coordinator from 2000 through 2004.
He landed on Mike Nolan's 49ers staff in '05
"And then finally having the opportunity to go out there (to San Francisco) and work," McCarthy said, "it was definitely a year that I enjoyed."
