As I recall, and I might be misremembering this, but in an article a few weeks ago, Peppers talked about how Mattison compared him to Charles Woodson quite a bit. I believe he also said that the Michigan staff has discussed using him in offensive packages as well.
I thought that it was interesting that he reminded you of Reggie Bush, but given the description and the highlight reels that have appeared here, that's really pretty apt. That, and a combination of Reggie Bush and Aeneas Williams (the CB you chose) would be a nice thing to have in the arsenal.
Thanks for sharing this, Magnus.
