I don't think there'd be much difference in recruiting, but it would make a difference if you were applying for jobs in the next few seasons after taking that hit. There is a minor risk of another schollie athlete leaving, but I think guyo's right, not a significant risk unless you already have a poor reputation (i.e. prior rescission, broken promises, etc.).
In answer to darnoc's question, I imagine there'd be some impact to cutting 9 sim-signed recruits, but it wouldn't matter unless you made the additional crazy choice of destroying that team to rebuild and then applying for another job the following season.
