Aaron Schobel and a FA like Chris Canty can help the DE situation. Ellison is a back up at best. Curry, Cushing or the other USC lb's are all better than Ellison. Is a rookie DE going to start over a healthy Schobel? I doubt it.
Frankly, I would take a DT like Raji who I also think is likely going to impact a game more than Kyle Williams who is also a backup at best.
So, no I am not kidding with passing on a DE.
