I would be opposed to scouting-based attributes or not having ratings for a couple of reasons.
For one, the scouting such that it is in this game right now for the draft is one of the weaker and less-fully fleshed out features in the franchise mode. The scouts don't have much (any?) personality other than a handful of numbers that aren't really well defined. Aside from this, scouting all of the players in the league on a regular basis would be such a tall task for 4 area scouts that you'd need a great expansion in the number of scouts...and you'd want more differentiation/personality in your scouts if they suddenly became much more critical to the player rating mechanic. I wouldn't want my entire knowledge of the MLB, or even a sizable chunk, to hinge on the limited scouting system that is currently in place. Now, if the scouting aspect were to get a lot of love and improve in the future, then I could see the draw to adding in a scouting component to ratings. Ditto for coaching, because the coaches are way too basic as just a source the same attribute boosts/nerfs no matter what player we're talking about.
Secondly, there is already "fog of war" in the current system. I believe you want something a little less cut and dried than looking at a rating number to make all roster decisions? But, even with "100% knowledge" of the ratings, some players will inevitably underperform and some will overperform. You will "like to hit" more with some players than others and some of this already feels quite unrelated to just the raw ratings. For example, sometimes I feel (placebo? perhaps) that I bat better with certain batting stance types than others due to having a larger/smaller strike zone and how the AI pitching attacks that specific player. So things like this, which are not based on ratings, can help drive my decisions on playing time and who gets key at bats. I also think you get a nice variety of outcomes in played and simmed games and it never really feels like because player X has contact rating of Y, player X must hit .260 or whatever.
And on some level, if you feel that just scrolling through for the highest CON vLHP is too boring, wouldn't scrolling for the highest Batting Average vLHP feel much the same? Wouldn't the process
still be basically reduced to looking at a single number whether that's a rating or a stat? Wouldn't you still be "managing a bunch of numbers" one way or the other?
I realize that you guys are both advocating for an
option to have this and I agree that having an option to hide ratings would be perfectly fine, but I'd only want it as an option and not the only way of doing things. And this POV is coming from a guy (or one of a handful of guys) who (1) enjoys playing a "stats only" set up in OOTP and (2) who's probably done more simming and testing the stats and ratings on recent MLBTS titles than anyone not working for SDS right now.
