The following Tweet is from Mike Barber, Tech beat writer for the Richmond Times-Dispatch.
Since it was reported by CoachingSearch.com during the bowl game, it has been a foregone conclusion that Sherman would join Darrell Hazell's new staff at Purdue.
In his column today, David Teel reiterated some assertions.
Presumed and unusual because head coach Frank Beamer has announced no changes to, or departures from, his staff. Yet fans, media and his colleagues believe (know?) he has decided to replace Bryan Stinespring as offensive coordinator and has green-lighted three assistants – receivers coach Kevin Sherman, guards/centers coach Curt Newsome and quarterbacks coach Mike O’Cain – to pursue other opportunities.
(His entire column is worth the read, by the way.)
Don't forget, Sherman's sports marketing agency, Coaches, Inc., already updated his bio to reflect the "pending" move (http://www.coachesinc.com/bio.aspx?id=117).
Why would Sherman have an option to return? I'm speculating here, but logically a world could exist where Beamer doesn't land his top guy (which we all believe to be Pep, and many of us think he would want a say in his staff), and any contingency plan or plans doesn't require as much turnover. Hell, a world could exist where Pep is a huge admirer of Sherman and wants him to remain. That's probably not very likely, but who knows.
