I don't think we necessarily have to go edge if the best talent at 15 is ILB. Both of those were equal needs before the offseason started.
Now that we have all but completely revamped the OLB position, ILB might actually be the bigger need.
Think back to the Lions game. Running backs in space have been eating us alive. I think if sheard can produce a 10 sack season, with Simon getting 4-6 and our rotational guys picking up some slack we will be fine without a Rd 1 Edge.
Now that doesn't mean we won't go edge in 2 or 3, however, I think getting a leader and 3-down ILB is essential to fixing this defense.
