Fantasy football position eligibility. Certain wide receivers may play running back (Randall Cobb and try Montgomery)
If a wide receiver takes snaps and carries out of the running back position they should have RB/WR eligibility. Similar to a baseball player having multiple position eligibility.

Ty Montgomery needs to be duel designated. You guys even gave a player update saying he's taken a full position change and moved to RB at this point. You guys are making yourselves fall behind other fantasy sites like NFL and ESPN
