When that Arizona Cardinals line up, wide receiver Andre Roberts is only on the field about 55-percent of the time over the last three games. TE Rob Housler came back from injury at that time and has since reduced Roberts' role to an afterthought. Roberts has just two catches during that three-game span.
In Week 1, Roberts posted a surprised eight receptions for 97 yards. Since then, he's contributed very little. The fourth-year receiver is no longer a fantasy option and is unlikely to become one again using this sort of gameplan. Until the Cards can find him an easier path to playing time, Roberts should absolutely stay a free agent in your league.
