We currently have one WR under contract. That one WR is approaching 35 years old and is now best suited for the slot. That one wide receiver is no longer a true #1 and can be used to mold his successor and a young guy that will grow and play with Cam for a long time. Wide receiver is the way we need to go assuming one of the top OT prospects doesn't fall right into our laps.
Teams are able to stack the box and focus on our running game because no one really respects our passing game outside of Olsen and an aging Steve Smith. We have no consistent deep threat and no one that can get valuable yards after the catch or break a game wide open. Our running game will improve as Amini gets healthy and competition emerges for the RG and RT positions after getting some guys healthy and drafting one more at those positions in the second or third rounds.
We will have a much clearer idea where we are going early in this draft after FA but we have ignored the wide receiver position for far too long. It is unlikely we find Gross' replacement at LT at #28 and I'd be willing to bet an impact WR can benefit this team right away compared to a rookie offensive linemen who will likely be on roller skates his first season and struggle against any upper-eschelon pass rushers. Last years top offensive tackles in the draft struggled all season long and while some mid-round linemen played well.
