Duke line dropping fast

What is up with this? Does anyone know if there is an injury update or something. Down to -12 at some places.

I see lines droppin' all over the place though

BC/Rutgers went from 5.5 to 6.5 in one minute.

 

BetRoyal has Duke steady at -14. Bodog where usually I bet dogs at has Duke at -13 and Olympic has Duke at -12.5. Weird to have that kind of difference in lines.

I thought the Duke line would move up, not down.
