This week, I have to go with my man Cole Beasley. He is only owned in 36% of fantasy leagues, and with Dez Bryant inactive he's a great pickup to plug any holes you might have at WR. (Especially in PPR leagues.)
Beasley is quickly becoming the 'Wes Welker' of the Dallas Cowboys, and is on pace to go over 1,000 yards this season! He has over 65 yards in each of the last 4 games and is cleary Dak Prescott's go-to guy.
Even if you play in a standard scoring league I think Beasley is worth a look at the flex spot this week as he goes against a porous Cincinnati Bengals defense.
