I can't disagree with you here as I also am a simmer, rather than a player, but AWR is the easiest attribute to raise, and even in a sim, is the one attribute per position that you have the most leniency on because everyone's awareness is lower when they first join the NFL and grows per year, so for scouting purposes it is not as important as it is when playing.
I guess what I'm saying is that it is the most coachable, so it is not as crucial to be high during the draft. I did my first two years scouting AWR first, also only checking out C+ players further on, last year I scouted on most important attribute per position and ended up having a better list than when I did scouting AWR first because although, true, like you said, high awareness usually means higher overall, it does not usually mean a better player for scheme. If you scout AWR first, you may be getting an average higher overall player, but you will be missing out on the superstar players for your scheme. In other words, you will get the
safer overall picks scouting awareness, but you will miss out on a lot of superstar
specialists.
P.S. Also remember AWR is more important generally for Defensive players than it is for Offensive players. Really the only position on O where AWR is even a concern is FB. OL some but not as much as FB
