You should be able to sway him down in this case. If he has Early playing time as Most and I'm a D, I should be able to sway him down from the Most to maybe average as a real life coach might be able to talk a recruit into realizing early playing time isn't that important.
Now to make this worth while you need to be able to get more recruiting points for matching up with a prospects interests, not just matching with his highly rated ones. In your example about the 3 star not opting to go to OSU, I completely agree with. But if that recruit has program prestige Low because he just doesn't want to go to that high end school and I'm a MAC school and my program prestige is C or B- I should be able to pitch that to him and get a significant amount of points.
The way the engine is right now you get more points based on how high the ratings are when that shouldn't be the case. It should be based more on matching ratings to the recruits ratings. Right now if I'm a A+ in something and the recruit has it at low I can still pitch it and get 50ish points, but if say Early PT is D and the recruit is low I get like 15.
