Every year, the Ravens go back and look at each scouts’ initial grades on prospects and then compare them to how they’ve performed in the NFL after getting an adequate sample size. This is a collaboration between the college and pro scouts.
There are so many different attributes that players are graded on, and the Ravens go back to evaluate scouts’ final reports on players, and where they were ranked on the board, to see if too much weight was placed on certain qualities.
Baltimore also runs checks to see if they simply aren’t valuing certain positions enough (or are overvaluing others).
