I was just thinking about a situation from Hard Knocks where all the coaches are sitting around the table discussing who is going to get cut. They ask the RB's coach what RB is the most expendable. Ask the LB's coach if he would miss a certain player.
I was thinking about a scenario where ratings, are for the most part hidden or maybe visible but not absolute (says 89 but could be anything from 75-99). And then during preseason when the cut days come you go through some sort of interaction with these position coaches on who they'd suggest you cut but ultimately you make the final call if you so choose. Kind of like position battles but a little bit different.
You could give coaches different ratings for things like identifying talent, developing players, etc.
