You can now search recruits based on their total rating or rated using your position role ratings. First, you want to make sure that you have your position role ratings set up. You can use either the basic mode or the advanced. On the recruiting search page, if you have selected a position you can then set whether you will see player's based on their Total Overall rating or one of your position role ratings.
For example: (using Advanced Position Roles)
Choose Quarterback position and then on the Overall Rating criteria allows me to choose from Total, Quarterback, QB Rushing, QB User 1. I'm looking for a rushing QB so I select QB Rushing. My first Order by will be by Overall Rating and then I want to order by Work Ethic so I select Then By Work Ethic. When I search I will see players listed by their QB Rushing rating now instead of their Total rating.
Also, if you really like the GUESS ratings or have your own, you can adjust your position roles for them or use them in the extra User role setting for most positions.
