Per Breer, "Another name to watch as a potential trade target this weekend would be Dalvin Cook. The Vikings have been communicative with their star tailback—and receptive to the idea of bringing him back—but it just won’t happen at the rate of $11 million he’s due this fall."
Breer goes on to say that the Vikings haven't shopped Cook, but if they land a running back in the first two days, Cook could be gone by the weekend. In this scenario, they will likely land a talent superior to that of Alexander Mattison, which hurts his value just as much as it helps. A third-round RB in Minnesota would be an immediate fantasy asset.
