Front 4 is soft. Oliver is 8 games away from being declared a bust. Edmunds is clueless and if he wasn't a first round pick he would have been benched mid-season.
They need to purge most of the free agents they signed last year and shed some salary. They should draft DT and Edge next year and add one free agent DT. That will give them Hughes in his final NFL year, Harrison, Oliver, Star, Epenesa, Zimmer, Butler, a vet, and 2 rookies.
