If it is not broken. don't fix it according to Minnesota Vikings OC Pat Shurmer. It is on that front where Shurmer confirmed on Thursday that rookie running back Dalvin Cook would remain the workhorse back in Week 2. Having picked up 137 total yards in the opener where the Vikes blew out the New Orleans Saints, Cook now takes on firm RB 1 value in fantasy football terms. With Cook having excellent receiving skills to go with his tough running style, he carries even more potential value in PPR formats. No matter the format, Cook is a must start everywhere.
