Most teams need to field more than one quality LB to have a good defense, and take note that roquan smith was drafted 8th overall and PQ went mid 20s, and roquan is 2 more years experienced. One was a developmental player and the other was projected to be the next great LB and they were both drafted accordingly, and shockingly both played out according to plan.
Adding the best ILB in the league to our more attack oriented developmental LB does not make that developmental LB a bust. Not being an all pro and making typical young mistakes within your first 2 seasons does not equate to bust
