I think the "surprised" quote has become boilerplate. Something to throw out there that may or may not be the reality but answers the question while giving away nothing. He used it too often otherwise. He's also an vet coach with a Super Bowl win, so he can admit to missing something. I don't think its easy for M3 to admit this is 2006-2009.

However, since the Packers new 4-3 has had some big leaks, I would be stunned if teams aren't just running new stuff to take advantage of what other teams expose.
