"Recruiting Promises
Many players want to get on the court right away. Once you've built up a certain amount of recruiting credit for a recruit, you can promise a starting spot or minutes. These options are free and valuable, but must be honored if the recruit signs, or he will react negatively and possibly transfer."
"Q: What if I guarantee a recruit a starting spot, then I dont give it to him? Same with minutes, what if I dont give him his promised time? Are there any repercussions?
A: Yes, there could be. Players who are promised either a starting spot (and then are not started) or a certain amount of playing time (and don't receive it) will most likely lose Work Ethic and could end up quitting the team."
The top except is from recruiting guide. The second is from the FAQ's.
From this, there only seems to be a possibility of transfer or loss of work ethic, but no mention of how (if at all) it affects future recruits.
