At the 5 spot, only Stroud and Johnson really project. Paul Spicer, 6-4" 295 lbs and a solid run stopper is out there. He and Stroud were team mates at JAX, albeit in a 4-3. I am sure we will draft a 5 technique player but having a greybeard as your starter wouldn't hurt.
While OBD works on getting Jimmy Kennedy on board, I have real concerns about our ability to man the 5 technique and OLB roles.
At OLB we currently have Schobel, if he stays on, and Kelsay, and it remains to be seen if either can play from a 2 point stance and drop into coverage. The same holds true for Aaron Maybin, who everyone has seemingly anointed a starter.
Enter Greg Ellis, late of the Raiders who has averaged 8 sacks over the past 5 years while spending 4 of those years as an OLB in the Dallas 3-4. He is strong against the run and might be had for a short term incentive laden contract. He would bring a certain "been there, done that" aspect to the team and Chan should know him from his Dallas days.
I would prefer we look at this D and add some established vets to the mix now or we will see our front 7 on D turn into last year's OLine experiment, where injuries and a lack of depth doomed our season.
