Overall I think the guy up top the Rams are going to want is Styles. He's the guy who plugs in and adds badly needed speed to our second level, improves coverage with his drops, and can play every snap. He's the piece that would be worth a move up because we probably have a completely different defense with him in the middle of it.
And this is a really nice ILB class. I like a lot of them, more than I usually do. But none of them are the total package he is.
Downs as you mention runs into issues with Lake and who's in what role. Now maybe the Rams want one of them for that other role who knows. But in terms of projecting likelihood yeah it seems like Downs is not the one they're going to covet. Nothing against Downs there either. He's a hell of a player just not the guy they'd jump for.
To jump for a player I think he has to have a clear role for this team.
Our needs should change after FA, or so I would hope. But for right now they are CB > Edge > Swing OT > WR3 > iOL > Safety. Roughly speaking and that's assuming most of our pending FAs leave.
So translating that to the early going, Delane is a top need with value, either of the projected OTs would be if the Rams like them, but are any of them worth jumping for? Probably not. The Edges are loaded of course and a big need if Young leaves in FA, but the depth of the class is so great that you'd have to really be hot for one of them to jump. So possible they jump for an Edge.
And I know someone will say well ILB is not a need. And it's not, in terms of being a position the Rams avoid paying, and have never drafted high under this regime. But great players always have the ability to change that equation.
