2002, jerkoff steve martin is listed as NT.
No such designation in 2001, lots of DE/DT, Hamilton has 79tackles instead of mid 50s.
Seems like they used a 4-3 for a while more than they wanted to take advantage of Hamilton's experience.
They also had McGoo switch from OLB/DE on the fly, of course.
Seems like they committed to the 3-4 in 2002, but used what worked best based on personnel.
