I would pick up Flacco as well.....even though you have Brees and he is an always/everyday/everytime starter Flacco should be a great Bye-week filler or trade bait! (I would drop Heyward-Bey......even though you have a ton of RB's I think that they are decent RB options and so if you don't want to drop a WR then try trading a couple RB's for an upgrade somewhere and then grab Flacco but I'll bet he won't last on the WW so........I would drop Bay and grab Flacco and then try and make a 2RB.....let's say Caddy or Knowshon and a backup like Brown/McCoy to the owners for a good WR or a better RB).....then grab a WR off the WW with the extra spot.
I would also grab the Jets Def as they looked tight in week 1 and should be great this year. Good Luck!
