Is it harder for a defensive back to lead the league in picks or defensive lineman lead the league in sacks?

As a defensive tackle id have to say that they both are difficult to lead. if your playing DB then your job is to cover the reciever so well that the ball is not ped in your direction making it difficult to get interceptions. As a D-lineman, your up close and personal, much more technique that has to be perfect and the QB can usually see you coming so you better haul ***. Either way its kinda a rough balance between luck and skill...
