I did some research on front-7 players for Kiffin's defense.
In 2012 Chicago and Seattle had Defensive Coordinators that were previous Kiffin assistants.
Kiffin's last year in Tampa Bay was 2008.
WDE - Similar to a 3-4 OLB. (Ware's new position)
SDE - Similar to a 3-4 DE. (Red Bryant in Seattle, 6-4, 323)
WDT - A gap-penetrating inside player (made famous by Warren Sapp).
SDT - A 1-tech. Takes on double-teams but is a 1-gap player.
While the "Weak" side linemen tend to be smaller than on the Strong-Side, that's not necessarily true with the LBs.
