Update: Vannini now says Spencer is "weighing his options" and it's not a done deal yet.
According to the generally reliable Chris Vannini of CoachingSearch.com, the Tampa Bay Buccaneers are losing running backs coach Tim Spencer to Lovie Smith at Illinois. Spencer's exclusively worked with Lovie Smith ever since he joined him in Chicago in 2004, so the fact that he wants to stay with him isn't necessarily all that surprising.
Losing Spencer in March is bad enough, as finding a new running backs coach isn't going to be very easy at this point in the offseason.
