i think ILB is pretty important in our system. our zone, or whatever the hell it is, leaves the ILBs responible for the whole middle of the field. we've seen for 5 or 6 years now that teams can almost trow at will on us over the middle
it may not me as important as a lot of the other positions on defense, but you can't just neglect it either
and TT has spent high draft picks on every position on defense EXCEPT ILB (hawk was drafted as a WLB for a 4-3)
