I think they need more experience at positions than they need to just fill holes. I'd rather they get an experienced edge rusher than rely on a guy they need to depend on right out of the gate. I feel the same for center. The only immediate starter I think the Rams should draft is maybe ILB. Other than that I think they'll:
draft tackles and/or a center to develop for next year
draft a gadget type receiver or running back, or a receiver they can slowly bring along (although I think Jefferson is that)
Draft an edge rusher but later (round 3 or beyond) as Lewis/Obo insurance
Draft inside linebacker--against the grain for them but this is the only position where I think they could use some dynamic youth and don't have many other good or guaranteed options. Jabril Cox and Baron Browning are my targets at 57 unless a really elite talent falls
