I assume that you’re referring to FA additions only here, Rock.
Even there, we may see a move at WR or RB, even possibly at TE before the dust settles. All depends on who they like among 2nd or even 3rd tier options.
As others have said, McVay probably isn’t done tinkering with his O pre-draft. He’s left several bread crumb clues about his desire to modify his TE attack, for example, so we should assume that he’s serious.
We’re down to just 3 needs as starters on D, IMO. If Suh should be signed, that would leave only an Edge LB and an ILB to go.
That means that the remaining picks can and probably will be devoted to depth players for development for future starter status.
Some of them will inevitably be O players.
BTW, let’s don’t forget that there is a lengthy period after the draft where FA’s can be added to missing perceived holes. Surely some will be added this year and some of those will be on the O side.
