A.Brown
B.Marshall
D.Murray
J.Landry
J.Graham
J.Hill

B.Lafell
T.Coleman
J.Matthews

His team:

D.Brees
D.Thomas

J.Edelman
T.Benjamin
A.Dalton
T.Gurley
J.Thomas

Format: QB, WR, WR, RB, W/R/T, W/R/T (K, DEF, IDP)

.5 PPR

I feel like I need a sure thing RB week-to-week. Would like move Murray or Blount or Matthews and Graham in a 2-for-1 trade for Gurley. Good idea? Which players would you move?

Bonus question: Rivers has been money so far this year.. Do you think he keeps this up ROS?

Thanks!
