Michigan State has a transfer in or out about every other year. Off the top
of my head, I can recall Robin Ill, Jenny Whitehead and Amy Sibbernsen
transferring out, and Andrea Pollard, Jennifer Stroffe and Sara Villwock
transferring in during the last ten years. Whitehead and Stroffe completed
their bachelor's degrees before exhausting their eligibility, and
transferred to play one year elsewhere as a grad student.
