If everything we know is what we have now, then this is a quick summation of what to expect in terms of the starting 11 on defense.
DE - Justin Smith
DT - John Thornton
DT - Sam Adams (mostly on rushing downs, my guess is Shaun Smith would be the most likely passing down tackle)
DE - Robert Geathers (Duane Clemons was cut and Carl Powell is an unrestricted free agent)
LB - Brian Simmons
LB - Odell Thurman
LB - David Pollack
SS - Madieu Williams
FS - Dexter Jackson
CB - Deltha O'Neal
CB - Tory James/Keiwan Ratliff
UNLESS THE team goes to 3-4 then the front seven would look somewhat like this:
DE - Justin Smith
NT - Sam Adams
DE - Robert Geathers
LB - Brian Simmons
LB - Odell Thurman
LB - Landon Johnson
LB - David Pollack
