Two reasons you don't take a ILB with a high pick in round 1:

3-4 OLB'ers are rush ends. They are not considered pure Linebackers. They are "Tweeners". Jarvis Jones is NOT a pure linebacker. He is a pass rusher first.

That sounds better to me than a guy who plays the run. Especially given our three year trend of decreasing sacks.
