He has never been tested like this. And I don't believe we can discern a players actual personality or character through media coverage. I have no idea how he will react. Unlike Kampman, he can't be one and done.
However, the more likely scenario is that the Packers play him more at OLB/Elephant than force it. If for no other reason than Peppers isn't going to be hear for the length of CMIII's contract. And I still think the Packers and the coaches value him more than you might and will want him to be in a position to succeed if he continues to struggle.
