I hold the Chicago Bears franchise record for most career sacks, but I am also known for my outspoken personality and occasional off-field controversies. I was a first-round draft pick and quickly became a dominant force on the defensive line. Who am I?

1. I played college football at a major SEC school.
2. My jersey number was 99.
3. I was drafted in the top 15 of the NFL Draft.
4. I had a notable rivalry with a certain Green Bay Packers quarterback.
