The Facts: Norv Turner has resigned as the Vikings offensive coordinator. The Vikings will promote current assistant Pat Shurmur to fill the vacancy.

Diehards Line:The news was sudden and surprising. As Profootballtalk.com notes, no reason was given for the move or the timing, but it’s going to be yet another huge adjustment for a team which already lost a franchise quarterback (Teddy Bridgewater), traded for another one (Sam Bradford), put their former MVP running back on injured reserve folloing knee surgery (Adrian Peterson) and lost both starting offensive tackles (Matt Kalil and Andre Smith).
