I too am loving Foster this year as I drafted him in both my $$$ leagues, but I'm not loving him this week against IND. I'm worried that Indy will run the score up early and Foster will be taking a back seat during catch-up. Yes Turner Starts, and to compliment him I would go with Forte, IT'S Detroit, and until they prove they are not still Detriot then any RB is a good play.
As for your WR question I steered clear of Smith in all my drafts this year. I think Hicks will be the go to guy in NY this year. For your #3 I'd take Garcon or Meachum this week, but I give a VERY slight edge to Garcon.
