Scouting college players would be an interesting aspect to the sim, but the reality is that in the NFL, scouting is convoluted at best and yields random results (the JaMarcus Russells and Ryan Leafs vs. the Tom Bradys and Brock Purdys, anyone?)
However, there is also something to be said about Scouting tied to Intangibles (which could be tied to a player's Volatility). That is a stat that could be masked to make scouting more essential to the process. No need to have a Scouting rating tied to coaches, scouting should be a mid-week activity like Scouting Opponents' Offense and Defense. If you scout, you get a slight bump on unmasking a positional group's intangibles / volatility.
Each scouting session reveals a random 25% of that positional group's volatility. Those are then stored in a new page called College Scouting Report (no need to run down which 25% it scouted). Obviously, it would require 4 weeks of scouting that position to unmask all 100% of that group. 16 games across a season would allow you to fully scout your top 4 positions, or 50% of 8 positions, or whatever amalgamation you so choose.
That would add a nice little flavor on taking a risk on a highly projected player whose volatility you can't see, or a dart throw on a 7th round player and not having ANY clue as to their volatility.
