Notes:
Named Second Team All-Big Ten by the league's coaches and honorable mention by the media as a senior following a 2007 campaign in which he posted a career-best 61 tackles...Mattison made 11.5 stops behind the line of scrimmage this past season and was credited with nine sacks, both of which were career highs...Over the last two years, he logged a total of eight forced fumbles for Iowa...Mattison posted 171 total tackles in his career, 33.5 tackles for losses and 20 sacks...Manages to do everything well, but doesn'texcel in any one area, with speed to force his way up the field or around the corner being something of a concern.
