re: Is it safe to drop AP yet?

That depends. Do you need the roster spot? Who is available to replace him with that roster spot?

I dropped him in two leagues where I needed the spot to pick up someone who would help me. I'm only keeping him in one league. The only reason I'm keeping him in that one league is I don't need the roster spot and there's nobody in FA that interests me much.

My roster:
QB: Luck, Sanchez
RB: Shady, L Bell, Jennings, D Robinson, Peterson
WR: Jordy, Jeffery, M Evans, J Matthews, D Adams
TE: Gronk, Rivera

Top Available FAs:
RB: FJax, Sims, Hillman, L Murray
WR: Percy, Randle, Hurns, Stills, Landry

I don't really see anyone but Peterson being able to break into my starting line. So for that reason I'm keeping him for another week just to see. Next week I might drop him and pick up someone else for depth.
