Just received an email from Informed Athlete about this rule change (highly recommend getting on Rick's mailing list). I can't believe this is the first I'm hearing about this rule change. Seems like a huge deal.
"Incoming freshman college athletes who have enrolled in summer school and received athletics financial aid can transfer and play immediately without a waiver if their head coach departs before the first day of classes for the fall term. Additionally, walk-on student-athletes on teams that provide athletics aid and nonrecruited walk-ons can transfer and play immediately without a waiver. Those rules are effective for students who transfer to new schools this fall."
