NRC got paid. Good for him.
I can only figure that a) he was brought here in the first place because Wade wanted him, and b) he is staying here with a shiny new contract because Wade wanted him.
He's a pretty good slot corner. If you believe in PFF's analytics (and I think some teams do buy into them or at least their methods), then NRC graded out as a top flight nickle last year.
But $5 mil per year isn't cheap. PFF guessed he'd get about $1 mil. Mostly because he's small and isn't well known. Clearly the Rams like what they have in the Secondary and plan on keeping it together as long as possible. Let's face it; on paper it is pretty formidable.
Now they just need to be sure to get a pass rusher or two.
