If we draft a guy like Tyson Jackson, the expectations won't be for him to produce Double Digit Sacks. 3-4 defensive ends are just supposed to keep contain on the Quarterback and keep lineman off of the linebackers. That's it. Tyson Jackson is very good at doing that, and he constantly drives lineman into the backfield to collapse the pocket.
I agree with G that Moreno is the safest pick.
