In my 1/2 PPR league, I'm playing a high scoring team and feel I need to take some chances. Currently using D Booker and T Rawls at RB, Julio, Tyreek Hill and Jordan Mathews at WR. Thinking of adding Malcolm Mitchell for either Hill or Mathews. Have Dion Lewis, Tevin Coleman and A Robinson and can substitute a WR FOR a third RB.
I'm okay going with Mitchell instead of Matthews, but otherwise I think I would go wtih what you've got. I think Hill is going to have a good game, and while Matthews is safer if he plays, I've been impressed with what I've seen out of Mitchell the last three weeks and am using him, despite the risk.
