So it looks like the Big 10 is undergoing a big change on staffs. Any idea of where the former assistant went and who is filling their shoes: Northwestern Ohio State Wisconsin Iowa (There seems to be a very high turnover on this staff in the past 3 years.) Indiana
Assistants don't make much $$, so there are very few that stick around very long. They're either looking for their own gig, or they find another line of work. UNC is pretty much the exception; although there are probably others.
The assistant at Northwestern left to become the head coach at Harvard. Below is a link to the information Stephanie Erickson . http://nusports.collegesports.com/sports/w-soccer/spec-rel/042905aab.html
OSU has filled their assistant coach vacancy: http://ohiostatebuckeyes.collegesports.com/sports/w-soccer/osu-w-soccer-body.html
