We desperately need to improve the speed, athleticism and versatility of the defensive front 7. There isn't just one position that needs to be upgraded. The entire unit is slow and lacks athleticism. While everyone else is infatuated with the idea of getting some fat guy to play NT and moving Ratliff to DE, I would be more focused on getting smaller and faster. I would cascade players inside to improve the overall speed of the unit. Moving Spears inside full time, moving Spencer to DE and getting an athletic OLB is more in line of what I'm thinking.
