On this issue...I think WIS has it right. You can rescind scholarships during the 2nd signing period. If you did not sign the recruit (auto-signed recruits included), then you will receive resources to recruit at the start of period #2. That seems right to me.
Now...the EE situation is different. I have repeatedly had the situation of staring at 2 guys that will go EE, but limited to 2 or 3 spots worth of resources to try to fill what will be 4 or 5 spots. The difference is the feeling that your results are not in your control, whereas the rescinding option you mention is within your control.
