We see this differently, Frantik.
Ebu is just not good enough. Left side, right side, it doesn’t matter. He's largely ineffectual as a pass rusher and is constantly being washed out on running plays. The tape doesn’t lie.
Now, if Fowler is reasonably extended then that’s one side. But an Ebu upgrade would still be essential. Obo is an enigma at this point. Hasn’t had one NFL snap, which maybe speaks volumes, so he has to prove himself on the field. Problem is that we can’t gamble that he’s a capable starter at this point. In fact, we must assume the opposite. So, another quality starting edge will still be necessary. Trade, FA, or draft, I don’t care. But Snead’s gotta get it done.
I agree that an ILB is also a high priority. It just is. One must come from the outside, one way or another.
Add in a DLreplacement for Suh and a S replacement for Joyner and we’re pretty much set for our starting D. For ‘19, anyway. As in Top 5, I think.
