True talk Pirk.  Also a huge neglected factor in predicting rounds/assigning pre-draft grades to prospects is the weighted ranking, i.e. volume of players per round.

 

We commonly hear a scout or team say 'we gave him a 2nd round grade'.  Did you only give 32 players this grade?  Or 40 players of comparable quality.  Due to this discord in quantity of players with similar grades, hence the fall of some to later rounds.  

 

In this example, you'd have 8 players who'd be perceived to have slipped.  Not due to talent reasons but a simple numbers game.
