Robert Foster will compete to be the No. 4 receiver in Buffalo this season, but he has minimal Fantasy value in that role. He should not be drafted in any leagues. The Bills' top three guys on the roster are set with Stefon Diggs, John Brown and Cole Beasley. Foster will compete for the No. 4 role with Duke Williams, Isaiah McKenzie and rookies Gabriel Davis and Isaiah Hodgins, but even if Foster wins that job he won't produce enough stats on a consistent basis to matter in most formats.
