Player Role Scouting Trip (or Head Coach Scouting Trip): In the recruit search function there is a dropdown menu labeled "Overall Rating". It allows you to sort by your user-defined player roles. The Head Coach Trip would require the user/coach to simply check the box, and then choose from that same dropdown menu. The cost would be something like 33% above a regular scouting trip (and may, or may not, count for additional effort over a regular Asst. Coach ST), but the user-definitions would be applied to weight the likelihood of responses received to the identified role. So, I've include a table below to show examples of how this would work.
I make the assumption that the likelihood of receiving any particular response on each of the 4 draws is identical: 1 in 12 or 8.333% [In the table, I gave the SF have this definition.] If true, then the odds of receiving the desired category response on a standard scouting trip are 33.3%. The tables assume that we want to know Speed potential, but work from the results that first REB, DEF & PER are chosen and next that ATH, LP & ST are chosen. The reason I did that is just a mental exercise for weighted odds on the final odds in favor.
[It makes sense to limit any particular response on an individual draw to ~20%, which, as the table shows, gives a final odds over 4 draws of ~62 - 66% of receiving a response in the desired category. On the other side, there at least must be a default chance (here 1 is selected) of receiving a response on FT or IQ.]
Conclusion: IMO, the ability of the coach to send a scouting trip in which user selected categories received a much greater likelihood of receiving a response (33% pushed up to ~66% as a cap) would dramatically improve user satisfaction with the scouting process, without disrupting the current gameplay of recruiting. On the gameplay side, this would effectively mean that you are able to tell an assistant coach "I am looking at this guy as a guard...I don't care if he can improve in REB or LP!"
User/coaches would not need to know how the sausage was made, but the ability to use the player roles to weight the probable responses to a scouting trip would be a subtle, but big improvement. Also, the fact that such a trip would be a little more expensive and would need to be assigned 1 at a time, would limit unintended consequences. User/coaches would likely employ a mix of regular scouting trips and 1 Head Coach/Player Role scouting trip each cycle.
