I assume you are referring to the two SFs. Yes it is related to playing time and at some point they will send you a letter regarding same. The upperclassmen are always going to expect double digit minutes and your So. played more last season. At worst they will transfer but since you didnt recruit them there is nothing to worry about unless you want them to stay. Also, as a general tip, put questions like these in the main HD forum, you'll find the amount of responses and the response time to be greater and faster. GL.
