With Moreno out (whom I fortunately don't own), I've picked up both Buckhalter and Maroney (yep, had the spare roster space) for this week. Thus, I now have a few different options at flex:
Louis Murphy @ Ari
Buckhalter or Maroney vs. Indy
Bowe vs. SF
I currently have Murphy plugged in, but am seriously considering swapping him out for either Buckhalter or Maroney.
