Mattison had some comments about the D that Michigan Insider tweeted.
Mattison: Mike Martin will love this defense, as opposed to getting doubled all the time last year.
Mattison on DT Will Campbell: Perfect for the 3-tech, winning all group competitions, reminds him of Haloti Ngata. 12 days to Spring ball!
"Mattison says he was shocked in first few film sessions by the inability of players to watch film correctly. "
edit: well shit, I searched for it and got nothing, forgot about diaries.
