B Cooks (NE) or C Davis (TENN) (1 Viewer)

Which WR would you like to own long term? 

Dynasty

PPR

50 man rosters, full IDP, no contracts

Start 3WR (up to 5 with Flex spots)

By no contracts I assume that means you can keep a guy forever with no penalty or cap hit that elevates the value of one over the other.  Based on that I would probably go with Davis as the long term play.  The assumes you do not want or need to factor in this year at all.  This is strictly based on 2018 and beyond.
